GameDay DJ turns any iPhone into a stadium-grade PA system for youth baseball, softball, and T-ball — with more sports on the way. Pick a feature below for a step-by-step walkthrough with screenshots. New here? Start with Game Day — how you actually run a game.
Game day
Run the game from one screen — tap the batter and their announcer intro plays straight into their walk-up song, instantly.
Walkthrough →Cache every intro and song before you leave, then play the whole game in airplane mode with zero buffering.
Walkthrough →Tap a vibe and we auto-mix crossfading music to fill the dead air between innings — and step aside for walk-ups.
Walkthrough →Press and hold and your phone is a PA mic — your voice goes live through the field speaker, music ducks automatically.
Walkthrough →Air horn for the homer, sad trombone for the strikeout — 20+ effects from a tap, plus custom sounds you describe.
Walkthrough →Get sound to your field speaker, see the active route on the toolbar, and fix no-sound issues fast.
Walkthrough →Build your roster
Snap a photo and our AI builds the whole roster — every name, number, and batting position. Review, then save.
Walkthrough →Broadcast-grade voices that call each player by name. Free voices included, more characterful ones on Pro — plus voice effects and custom scripts.
Walkthrough →Trim every player's song to the riff or the drop with a waveform and zoom loupe — and balance the announcer over the music.
Walkthrough →Run every team you coach from one app — color-coded, sport-aware, each roster clean and separate.
Walkthrough →Set a different batting order for each game of the weekend without touching your master roster.
Walkthrough →Moving over? Screenshot your BallparkDJ team and scan it in — names, numbers, and songs come across in seconds.
Guide →Share & safety
One link, two roles — co-coaches edit the roster, parents claim their own kid and pick the walk-up song.
Walkthrough →Children's data, privacy-first — no third-party ad SDKs, optional explicit-song filter, one-tap data deletion.
Privacy policy →Baseball, softball, and T-ball at launch — sport-aware positions, terminology, intro cadence templates, and color presets.
Soccer, basketball, football, hockey, lacrosse, volleyball — we'll prioritize what coaches ask for. Drop your email and the sport you want and we'll let you know when it ships.
