OnDeckDJ pairs each batter with a custom walk-up song and an AI-generated stadium announcer voice. One tap on game day from your phone or your Apple Watch. No fumbling. No subscription.
For coaches, parents & team DJs at every level
Pro-grade walk-up music workflow, designed for the parent running the speaker — not a sound engineer.
Stadium baritone to energetic hype. Every player gets a custom intro by name and number, generated in seconds.
Pick walk-ups from Apple Music, your local library, or import MP3s. Pre-set the start point so you land on the chorus.
One-tap-per-batter playback. Big buttons, automatic queueing, volume ducking that snaps back. No fumbling.
Strikeout themes, home run horns, rally moments. Every situation has a tap. Use sparingly for maximum impact.
Optimized for outdoor portable speakers. No lag, smart volume, no dropped connections during the game.
Export your full roster — songs, intros, settings — and send it to any coach. They import it in one tap.
Run Game Mode from your wrist. Next batter, play, stop-with-fade, sound effects — all from a glance, hands free in the dugout.
Set up the lineup once before the game. On game day, you just tap.
Add players, jersey numbers, and pick a walk-up song from Apple Music, your library, or imported MP3s. Set the start point so you land right on the hook.
Tap "Generate" on each player and pick from 9 AI announcer voices. The app creates a custom stadium intro by name and number.
Connect to your Bluetooth speaker, open Game Mode, and tap each batter as they step in. Announcer plays, song fades in, volume ducks for the announcement, snaps back. That's it.
Add players in seconds. Reorder by drag. Pick the song, the start point, the announcer voice. Every detail saved automatically. Then export your full lineup — songs, intros, settings — and text it to the parent running the speaker for the next game.
From deep stadium baritone to energetic hype man, OnDeckDJ ships with 9 distinctive AI voices. Pick the one that fits your team's vibe — different voice per player if you want — or record your own voice for the most personal touch.
Strikeout themes, home run horns, walk-off rally cues. OnDeckDJ ships with a library of situational sound effects, each on a one-tap trigger. Use them sparingly — the right horn at the right moment turns a routine play into a memory.
The Apple Watch companion mirrors Game Mode — current batter, on-deck, play / stop / next, sound effects — all from a glance. AirPods and Bluetooth speaker controls also drive playback, so you can run the dugout hands-free.

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.
