The easiest way to play walk-up songs at a baseball game

Walk-up music turns a routine at-bat into a moment. The hitter's name booming through the speaker, their favorite song kicking in as they step to the plate — it's how Major League players get hyped, and now any youth baseball or softball team can do the same. OnDeckDJ is the iOS app that makes it ridiculously easy to set up walk-up music for every player on your roster, then run it from your phone with one-tap controls during the game.

Built for coaches, parents, and team DJs, OnDeckDJ pairs each batter's chosen song with an AI-generated stadium announcer voice that calls them to the plate by name and number — no recording studio, no audio engineer, no setup hassle.

Common questions

Is OnDeckDJ free?
Yes — free to start with one team and 15 AI announcer credits, which is enough to fully set up a 12-player roster. Pro is a one-time $5.99 unlock for unlimited teams and 200 voice credits. There's no subscription and no account required.
Does it work with my Bluetooth speaker?
Yes. OnDeckDJ is optimized for any standard Bluetooth speaker — JBL, Bose, Soundboks, etc. Audio routing, volume control, and ducking all work over Bluetooth. We recommend a 30W+ portable PA for outdoor games — see our full Bluetooth speaker buyer's guide for baseball for picks from $80 to $1,000.
Can I use songs from Apple Music?
Yes. OnDeckDJ integrates with Apple Music's catalog, your personal music library, and lets you import any MP3 directly. Pick any song and set the precise start point so the walk-up lands on the chorus.
What are AI announcer voices?
For each player, OnDeckDJ generates a custom stadium-style announcement using one of 9 AI voices — saying the player's name and number. The announcer plays before the song kicks in, just like a real ballpark. You can also record your own voice if you prefer.
Is it just for baseball?
Baseball and softball are the primary focus, but the app works for any sport with batter-by-batter or player-by-player walk-ups — including kickball, slow-pitch, intramural leagues, and more.
Does it work without internet?
Most features work offline. The only feature that requires internet is generating new AI announcer voices (one-time per player). Once generated, the announcer audio is stored on-device and plays without any connection.
How do I share my lineup with another coach?
Export your full lineup as a single .ondeckdj file and share it via Messages, AirDrop, or email. The recipient taps the file in OnDeckDJ and the entire lineup — players, songs, intros, settings — is imported in seconds.
