Getting Started
Where do I download SportsDJ?+
SportsDJ is on the App Store — search for SportsDJ. The app itself is free; SportsDJ Pro is a one-time purchase inside it. To put it on a second device, install it there with the same Apple ID signed in, then tap Restore Purchases on the Pro upgrade screen to get Pro back.
SportsDJ is on Google Play — search for SportsDJ. The app itself is free; SportsDJ Pro is a one-time purchase inside it. To put it on a second phone, install it there signed in to the same Google Play account — SportsDJ picks the purchase up the next time it starts, so there is nothing to restore.
How do I add sounds?+
Tap the + button on the home screen to open Import Sound, then tap Select Files and pick one or more audio files from Files, iCloud Drive or anywhere else the Files app can reach. You can also import from your Apple Music library. New sounds go into the group you have open.
Tap the + button on the home screen to open Import Sounds, then tap Import and pick one or more audio files. They're copied into the group you have open. The + button isn't shown while a sport group is open.
Which audio formats and sources can I import?+
Audio files in MP3, WAV, OGG, FLAC, M4A, AAC and AIFF format, and tracks from Apple Music. Spotify import is not available yet.
Audio files in MP3, WAV, OGG, FLAC, M4A, AAC and Opus format, and ZIP archives containing them. Spotify import is not available yet.
Where can I buy song files to download?+
SportsDJ plays files you own, so you need somewhere that sells DRM-free downloads rather than a streaming subscription. Bandcamp sells MP3 and FLAC, the iTunes Store sells M4A, and HDtracks sells high-resolution FLAC — all of them import, as does anything else in MP3, WAV, OGG, FLAC, M4A, AAC or AIFF. You can also skip buying files altogether and add tracks straight from your Apple Music library.
SportsDJ plays files you own, so you need somewhere that sells DRM-free downloads rather than a streaming subscription. Bandcamp sells MP3 and FLAC and HDtracks sells high-resolution FLAC — both import, as does anything else in MP3, WAV, OGG, FLAC, M4A, AAC or Opus. If a store hands you a ZIP of a whole album, import the ZIP and every track inside it comes in at once.
Can I import several files at once?+
Yes — after tapping Select Files, select as many files as you like. Importing a whole folder or a ZIP archive isn't available.
Yes. After tapping Import, select several files at once, or pick a ZIP archive and every audio file inside it is imported. To import a whole folder, tap Import Folder — that one requires Pro.
How do I import a file from Google Drive?+
Tap the + button on the home screen to open Import Sounds and tap Import — the file picker that opens can reach Google Drive. Open the picker's menu, choose Google Drive, then tap the file. If Google Drive isn't offered there, install the Google Drive app first. You can also go the other way round: open Google Drive, download the file to your phone, and import it from your Downloads.
How do I create a sound group?+
Tap the + at the end of the group tabs along the bottom of the home screen, choose a Group Type — Music, or a sport — and give the group a name. The free version has one group; more require Pro.
Tap the + at the end of the group bar along the bottom of the home screen, choose a type in New Group Type — Standard, or a sport — then name the group and tap Create. The free version has one group; more require Pro.
Can I use SportsDJ for free?+
Yes. The free version holds one sound group and up to 20 sounds. SportsDJ Pro removes both limits.
Playing Sounds
How do I play and stop a sound?+
Tap a tile to play it. While it's playing, a tap fades it out and a double-tap stops it at once. To change what those do, go to Settings → Playback and set Tap (Playing) and Double Tap (Playing), or change them for one sound under Tap Actions in Edit Sound.
Tap a tile to play it. While it's playing, a tap fades it out and a double-tap stops it at once. To change what those do, go to Settings → Tap Actions — Sound Playing, or change them for one sound under Tap Actions (while playing) in its settings.
How many sounds can play at once?+
By default, one. Settings → Playback → One Sound at a Time starts switched on, so playing a sound stops whatever else is going. Turn it off to layer sounds freely, or leave it on and turn on Allow Overlap in Edit Sound for the few sounds that should always play over the top — a goal horn, an air horn. There's no fixed limit on how many tiles can sound together.
By default, one. Settings → Playback → One Sound at a Time starts switched on, so playing a sound stops whatever else is going. Turn it off to layer sounds freely, or leave it on and turn on Allow Overlap in a sound's settings for the few sounds that should always play over the top — a goal horn, an air horn. Allow Overlap requires Pro. There's no fixed limit on how many tiles can sound together, but one combo tile plays at most 8 of its own sounds at the same instant and drops the rest.
What else can a tap do while a sound is playing?+
Restart, Stop, Fade Out, Pause / Resume, or No Action. A tap on a sound that isn't playing always plays it.
In Settings you can choose Stop, Fade out, Pause / Resume or None. A tap on a sound that isn't playing always plays it.
How do I loop a sound?+
Touch and hold the tile to open Edit Sound, then under Playback set Loop to a number of repeats, or ∞ to loop until you stop it. Looping works for imported files and Apple Music tracks.
Long-press the tile to open its settings and set Loop to a number of repeats, or Endless ∞ to loop until you stop it.
Can a sound start the next one automatically?+
Yes. Turn on Play Next on Complete in Edit Sound → Playback, and when the sound finishes the next sound in the group starts. In a Music group, touch and hold the group's tab and choose Group Settings — Auto-Advance there switches this Per Sound, On or Off for the whole group.
Yes. Turn on Play next sound when done in the sound's settings, and when it finishes the next sound in the group starts. For a whole group, long-press its tab, choose Playback, and set Auto-advance to Per sound, On or Off.
How do fade-in and fade-out work?+
Settings → Audio sets the Default Fade-In and Default Fade-Out for every sound. To give one sound its own fades, open Edit Sound and turn on Fade In or Fade Out under Playback; the lengths are set in Fades & Dropouts. Apple Music tracks can't fade.
Settings → Audio sets the Default Fade In and Default Fade Out for every sound. A sound's settings show which fades it uses; open Fades & Dropouts there to give that sound its own.
How do I change a sound's volume?+
Open Edit Sound and use the Volume slider under Playback — it's there for imported files. Master Volume in Settings → Audio sets the level for everything.
Turn on Show Volume Control in Settings → Appearance (it's off by default), and a volume slider appears in each sound's settings. Master Volume in Settings → Audio sets the level for everything.
How do I find a sound quickly?+
Tap the magnifying glass at the top of the home screen and type part of the sound's name. Search looks through the group you have open.
Tap the search icon in the top bar and type part of the sound's name. It searches every group at once and labels each result with its group.
Why are some tiles dimmed?+
SportsDJ dims a tile once it has played, so you can see what you've already used. To bring them all back, open the side menu and tap Reset Dimmed Tiles. Turn dimming off with Dim After Playing in Settings, or for one sound with Don't Dim After Playing in Edit Sound.
SportsDJ dims a tile once it has played, so you can see what you've already used. To bring them all back, open the side menu and tap Reset Dimmed Tiles — starting a New Game on a sport panel resets them too. Turn dimming off with Mark Sounds When Played in Settings → Playback, or for one sound with Don't Dim After Playing in its settings.
How do I change the tile size?+
In Settings, set Cell Size to Small, Medium or Large. It applies to sounds you import from then on.
Go to Settings → Appearance → Cell Size and choose Small, Medium or Large.
Editing Sounds
How do I open a sound's settings?+
Touch and hold the tile. Edit Sound opens straight away — there's no menu first. On a Mac, right-click the tile and choose Edit. Holding a combo tile opens the Combo Editor instead.
Long-press the tile to open its settings. Long-pressing a combo tile opens the combo editor instead.
How do I rename or color-code a sound?+
In Edit Sound, change the name under Name — Alt title, if you fill it in, is shown on the tile instead. For color, pick one of 11 presets or no color, or enter any Custom hex value. The color new sounds start with is set in Settings.
In the sound's settings, edit Name. Under Color, pick one of 12 preset colors or None, or enter a custom hex value. The color new sounds start with is Default Cell Color in Settings → Appearance.
How do I trim a sound?+
In Edit Sound, tap Fades & Dropouts. Drag the In and Out handles on the waveform to set where the sound starts and ends — zoom in for precision, or pick In or Out and nudge it with −1s, −100ms, +100ms and +1s. Tap Play to hear it, then Save. Trimming works for imported files and Apple Music tracks.
In the sound's settings, tap Fades & Dropouts. Set the In and Out points on the waveform to choose where the sound starts and ends, and tap Play to hear the result.
What are dropouts?+
A dropout silences or lowers a sound for part of its length — handy for a singalong, where the crowd takes over. In Fades & Dropouts, move the playhead to where it should start and tap Dropout. A dropout mutes by default; turn on Duck to lower the volume instead, and set how far with Duck to. Apple Music tracks support muted dropouts only.
A dropout silences or lowers a sound for part of its length — handy for a singalong, where the crowd takes over. In Fades & Dropouts, tap + Dropout. Each one can be Muted or Ducked; for a ducked one, set its Duck level.
How do I copy or move a sound to another group?+
In Edit Sound, tap Move to Group… or Copy to Group… and choose where it goes. They appear once you have more than one group. On a Mac you can also right-click the tile and choose Move to Group.
In the sound's settings, scroll to the bottom and tap Copy to Group or Move to Group, then pick the group.
What happens if I import a sound I already have?+
If the group you're importing into already has it, SportsDJ shows Already Imported and lets you Skip This Sound or Add to Another Group.
If the group you're importing into already has it, SportsDJ shows Already Imported. Pick another group and tap Add to Group, or tap Skip.
Groups & Reordering
How do I rename a group?+
Touch and hold the group's tab, choose Group Settings, and change Group Name.
Long-press the group's tab and let go without moving your finger. In the menu that opens, tap Rename.
How do I reorder the sounds in a group?+
Touch and hold the group's tab, choose Arrange Tiles, drag the tiles into place and tap Done. Or open the side menu → Manage Sound Groups, tap the group, and drag the rows.
Long-press the group's tab, choose Arrange Tiles, drag the tiles into place and tap Done in the banner at the top. Or open the side menu → Manage Sound Groups, tap the group, and drag the handles. Arrange Tiles is available in standard groups.
How do I reorder groups?+
Open the side menu → Manage Sound Groups, drag the ≡ handles, then tap Done.
Long-press a group tab and drag it to a new position, or open the side menu → Manage Sound Groups and drag the handles.
Combos
What is a combo tile, and how do I make one?+
A combo tile plays several sounds as one, each placed on a timeline in its own lane. To make one, tap + on the home screen and choose Create Combo Tile. To change it later, touch and hold the tile. Combo tiles require Pro.
A combo tile plays several sounds as one, each placed on a timeline in its own lane. To make one, tap + on the home screen and choose Create Combo Tile. To change it later, long-press the tile. Sounds in a combo come from the imported sounds in your standard groups. Combo tiles require Pro.
How do I move a sound along the timeline?+
Tap the clip to select it, then touch and hold it until it lifts and drag it earlier or later. The hold is what makes it a move: a plain drag always scrolls the timeline, wherever it starts, so you can pan even when the lanes are full. If the clip repeats, moving it moves the whole pattern.
Tap the clip to select it, then long-press it and drag it earlier or later. A plain drag always scrolls the timeline. For precise moves, use the −1s, −100, +100 and +1s buttons in the clip's settings.
How do I close a clip's settings?+
Tap the ✕ at the top right of the settings panel, or tap the selected clip again. Either one puts the panel away without changing which lane the next sound goes to.
There's no close button. Tap an empty part of the timeline — the clip is deselected and its settings go away.
Which lane does a new sound go into?+
The targeted lane, whose number is highlighted in the column on the left. Tap any lane number to target it. Selecting a clip also targets its lane, so a sound added after tapping a clip lands where you were looking.
The lane shown in the Adding to chips above the timeline. Tap a chip, or tap a lane on the timeline, to target a different one; selecting a clip targets its lane too. Tap Add Sound and the sound lands in that lane at the cursor.
How do I add or remove a lane?+
Tap Add Lane for another timeline. To remove one, touch and hold its number in the left-hand column and choose Remove Lane — on a Mac, right-click it instead. If the lane still has sounds in it you'll be asked to confirm. The sounds are removed from the combo only; your library keeps them.
Tap Add Lane for another timeline — a combo can have up to 8. An empty lane has a trash icon on its chip; tap it to remove the lane. A lane with sounds goes away once its last sound is removed — select the clip and tap Remove this sound. Sounds removed from a combo stay in your library.
What do the tinted spans behind some clips mean?+
They mark where two or more clips in the same lane play at the same time. That's allowed and often deliberate — it's highlighted so you see it here rather than discover it at a game. Clips in one lane share that lane's volume and ducking settings.
What does "Plays layer by layer" mean?+
SportsDJ normally mixes a combo ahead of time into a single sound so it starts instantly. Some combos are too large for that on this device, or contain a layer with no fixed length, so they play each layer separately instead. It sounds exactly the same — the note is there to explain why, not to warn you.
SportsDJ normally mixes a combo ahead of time into a single sound so it starts instantly. Some combos can't be mixed that way — they're too large for this phone, or include a repeating layer or a streamed track — so they play each layer separately instead. Such a tile says Plays differently — open this tile to see why, and the combo editor shows which reason applies.
Sports & Rosters
Which sports does SportsDJ support?+
Hockey, Softball, Baseball, Basketball, Football and Soccer. Choose the sport as the Group Type when you create a group — Music is the plain soundboard. The free version has one group, so adding a sport group requires Pro.
Hockey, Softball, Baseball, Basketball, Football and Soccer. Choose the sport in New Group Type when you create a group — Standard is the plain soundboard. The free version has one group, so adding a sport group requires Pro.
What does a sport group's panel show?+
A sport group replaces the plain grid of tiles with a panel built for that sport. • Hockey — score, period, a game clock, and a goal and a penalty button for each team, with penalty clocks. Shot and penalty counters can be shown or hidden in the group's settings. • Softball and baseball — the batting order, with NOW BATTING, ON DECK and IN THE HOLE, and the current batter's walk-up. • Basketball — score, period, team fouls, a game clock and action tiles. • Football — score, quarter, down and distance, a game clock and action tiles. • Soccer — a panel you put together yourself. It starts with two scores, a half counter, a count-up clock, yellow and red card counters and a grid of tiles, and you add, remove or reorder those in the group's settings.
What are action tiles?+
An action tile plays from a whole group rather than from one sound, so each tap can pick a different track — useful for crowd hype or between-play stings without building a grid of them. Make one from + → Action Tile; creating one is free, though it counts towards the free version's 20-sound limit. Touch and hold the tile to choose which group it Plays From and whether its Order is Random, Sequential or the group's own default. Basketball, football and soccer panels carry action tiles of their own, set up in the group's settings.

How do I set up a team and its walk-up songs?+
Open the side menu → Teams & Rosters to create a team and add its players. For softball and baseball, open the lineup editor from the group's game panel and link each player to their walk-up song.
Open the side menu → Teams & Rosters to create a team and add its players. For softball and baseball, open the group's Lineup Editor to set the batting order and pick each player's walk-up.
Can I import a roster from a spreadsheet?+
Not yet. Open the side menu → Teams & Rosters, open the team, and add players one at a time with the add-player button at the top right.
Yes, as comma-separated text. Open the side menu → Teams & Rosters, open the team, and tap the upload button above the add button. Paste your roster one player per line as Name, Number, Position — the number and position are optional, and a line starting with # is skipped as a comment — then tap Import. Save your spreadsheet as CSV first: text pasted straight out of a spreadsheet arrives separated by tabs, and the whole line lands as one player's name.
How do I play a player's walk-up during a game?+
In a softball or baseball group, tap a batter to make them the current batter, then tap PLAY WALK-UP. Tap STOP WALK-UP to end it early.
In a softball or baseball group, the panel shows who is NOW BATTING, ON DECK and IN THE HOLE. Tap PLAY WALK-UP to play the current batter's walk-up, and STOP to end it early.
Mic Announcements
How do I make live announcements with the microphone?+
Go to Settings → Announcements and turn on Mic Announcements. A mic button appears on the home screen; how it behaves depends on the Interaction Mode you choose there.
What do the mic interaction modes do?+
• Toggle — tap the mic button to go live, and tap again to stop. • Hold to Talk — the mic is live only while you hold the button. • Smart (Auto) — tap to go live; the mic turns itself off after a moment of silence. It does not switch on by itself when you start speaking.
• Toggle — tap the mic button to go live, and tap again to stop. • Hold to Talk — the mic is live only while you hold the button. • Smart — tap to latch the mic on and tap again to stop, or hold the button to talk only while you hold it. Smart is the default.
Can the music duck while I talk?+
Yes. Turn on Duck Music While Announcing in Settings → Announcements, and other sounds drop to 15% of their volume while the mic is live. Mic Gain, in the same place, makes your voice louder or quieter.
I hear feedback or echo when the mic is on. How do I fix it?+
Feedback happens when the microphone picks up the speaker it's playing through. Keep the phone away from the speakers, turn Mic Gain down in Settings → Announcements, and use a wired connection to the sound system where you can — Bluetooth adds a delay that makes echo easier to hear.
Bluetooth & Footpedal
Why does my Bluetooth speaker cut off the start of sounds?+
Many Bluetooth speakers doze off after a moment of silence and need a split second to wake up, which clips the start of the next sound — some play a reconnect beep as well. In Settings → Bluetooth, turn on Keep Alive to play an inaudible silent loop that stops the speaker sleeping, or Warm Up Connection to play a short silent lead-in before each sound, and raise its Duration if the start is still clipped.
Many Bluetooth speakers doze off after a moment of silence and need a split second to wake up, which clips the start of the next sound — some play a reconnect beep as well. In Settings → Bluetooth, turn on Keep Bluetooth Awake to play an inaudible silent loop between sounds, or Pre-Roll Warm-Up to add a short silent lead-in before each one, and raise Pre-Roll Duration if the start is still clipped. The Bluetooth features require Pro.
Can I use a Bluetooth foot pedal?+
Yes. Pair the pedal with your device, then go to Settings → Input → Configure Footpedal. Each of Pedal 1 to Pedal 4 has a Learn button: tap it, press the pedal button you want to use, then choose what that pedal plays.
Yes. Pair the pedal with your phone, then go to Settings → Bluetooth → Configure Footpedal. For each pedal button, tap Learn and press the button on the pedal, then assign it a sound group — each press plays the next sound in the group — or a single sound. Requires Pro.
Widgets
How do I add a Home Screen widget?+
Touch and hold an empty area of your Home Screen, tap Edit, then Add Widget, and choose SportsDJ. There are three widgets: SportsDJ Sounds, Hockey Controls and Walk-Up Music. Set yours up in Settings → Widget → Configure Widget. Widgets require Pro.
Long-press an empty area of your home screen, tap Widgets, find SportsDJ and drag a widget onto the screen. There are three widgets — Soundboard, Walkup and Hockey. Tap a button on a widget to trigger that sound without opening the app. Widgets require Pro.
Which watches are supported, and how do I use the tile?+
Any watch running Wear OS 2.0 or newer — a Pixel Watch or a Galaxy Watch, for instance. Install SportsDJ on the watch and add the SportsDJ tile from the watch's tiles. On your phone, go to Settings → Watch Tile → Configure Watch Tile to choose what its buttons play — up to five, each a group or a single sound, plus Stop. Requires Pro.
Is there an Apple Watch app?+
Not yet. To trigger sounds without opening SportsDJ, use a Home Screen widget.
Backup & Restore
How do I back up my sounds and groups?+
Open the side menu → Backup & Restore → Export Backup. Choose the groups to include, or Select All, and a file name if you like. SportsDJ makes a .sdj file with your groups, sounds and settings, which you can save to Files or iCloud Drive or send to another device. Requires Pro.
Open the side menu → Backup & Restore → Export Backup. Choose the groups to include and a backup name if you like, then pick where to save the .sdj file — on your phone, in Google Drive, or anywhere else the save screen offers. Requires Pro.
How do I restore from a backup?+
Open the side menu → Backup & Restore → Restore from Backup, pick the .sdj file, then choose which groups to bring in, or Import All. You can also open a .sdj file straight from the Files app or AirDrop. Requires Pro.
Open the side menu → Backup & Restore → Restore from Backup and pick the .sdj file. You can also open a .sdj file from your Files app — SportsDJ asks Restore from backup? first. Requires Pro.
Will restoring a backup replace my current sounds?+
No — restoring merges the backup into your library. If a group with the same name already exists, choose whether to rename the restored one, overwrite the existing one, merge into it, or skip it. For sounds you already have, choose Keep Both, Skip Duplicates or Overwrite Duplicates.
No — restoring merges the backup into your library without overwriting what's there, and conflicts are settled one at a time. A group with the same name can be merged, renamed with (Restored), overwritten or skipped; duplicate sounds inside it can be kept, skipped or overwritten; and a team with the same name can be replaced, skipped or imported as new.
Why won't my .sdj file open from Google Drive?+
Google Drive's file picker can fail silently on large backup files — tapping the file may do nothing, or the file may not appear at all. This is a Drive limitation, not a SportsDJ one. Download the .sdj file to your phone first (in Drive, tap the file's menu and choose Download), then restore it from Backup & Restore → Restore from Backup. Files stored on your phone always work, whatever their size.
Troubleshooting
Sounds aren't playing. What should I check?+
Turn the volume up with the side buttons while SportsDJ is open, and check where the audio is going — a connected Bluetooth speaker or headphones will take it. Then check Master Volume in Settings → Audio and the sound's own Volume in Edit Sound. Apple Music tracks also need an internet connection and an active Apple Music subscription.
Turn the media volume up with the volume buttons while SportsDJ is open, and check where the audio is going — a connected Bluetooth speaker or headphones will take it. Then check Master Volume in Settings → Audio.
Why does Apple Music say I need a subscription?+
Playing Apple Music tracks in SportsDJ needs an active Apple Music subscription on the Apple ID signed in to this device.
Apple Music tracks hang or the library appears empty.+
SportsDJ needs permission to use your media library. In the Settings app, go to Privacy & Security → Media & Apple Music and make sure SportsDJ is turned on. If it already is and the problem continues, contact support from this screen.
Why does audio stop when I lock the screen?+
It shouldn't — SportsDJ keeps playing while your device is locked, and its Now Playing notification offers Fade Out and Stop All. If audio stops, another app — a phone call, or a music app — has probably taken over the audio; start the sound again from SportsDJ.
SportsDJ keeps playing in the background as long as Allow Play in Background is on in Settings → Playback, which it is by default. If playback still stops when you lock the screen, check that the app isn't restricted in your phone's settings (Settings → Apps → SportsDJ → Battery) and that SportsDJ hasn't been force-stopped.
The app is slow or sounds are cutting out.+
Close other apps running in the background. Imported files are stored on your device and play without an internet connection; Apple Music tracks stream, so check your Wi-Fi or cellular connection.
Close other apps running in the background. Imported files are stored on your phone and play without an internet connection.
I can't find the file I want in the file picker.+
Tapping Select Files opens the Files app's picker, so the file has to be somewhere Files can reach. Tap Browse at the bottom and pick a location — your device, iCloud Drive, or any cloud service whose app you have installed; if a service isn't listed, turn it on from Browse in the Files app. For an iCloud Drive file, make sure it's downloaded to your device first: in Files, touch and hold the file and choose Download Now.
Walkthroughs
Combo Editor Walkthrough+
Lanes, moving a clip, and what the marks mean
Every Lane Is a Timeline
A combo plays as one sound. Each lane runs left to right, and holds as many clips as you like at any positions you like — a second lane is for sounds that play at the same time.
Drag to Scroll, Tap to Open
Dragging anywhere always scrolls the timeline — on a clip, on empty space, it never matters. Tap a clip to open its settings, and tap it again to put them away.
Hold a Clip to Move It
Tap the clip first, then touch and hold it until it lifts, and drag it earlier or later. If the clip repeats, the whole pattern moves together — it is one clip, played more than once.
Choose Where Sounds Land
The highlighted number in the left column is the lane the next sound goes into. Tap any lane number to aim there. Tapping a clip aims at its lane too, so a sound added next lands where you were already looking.
Add and Remove Lanes
"Add Lane" gives you another timeline. To remove one, touch and hold its number in the left column and choose Remove Lane — right-click it on a Mac. The sounds leave the combo only; your library keeps them.
Tinted Spans Play Together
A tint behind two clips in one lane means they overlap and sound at once. That is allowed, and often the point — it is marked so you see it here rather than hear it at a game. Clips in a lane share that lane's volume and ducking.
"Plays Layer by Layer"
SportsDJ usually mixes a combo ahead of time into one sound so it starts instantly. Some combos are too large for that on this device, so they play each layer separately instead. It sounds the same — the note explains why, it is not a warning.
