Walkup songs, AI announcer intros, personalized playlists, and a soundboard built for the dugout. This is what game day audio looks like when it's done right.
Demo accessRequest early access→There's a special kind of energy when a player's song hits right as they step in. Diamond DJ makes that happen reliably every time — so easy to use you'll never look back.
Easy to set up. Easier to use. None of the headaches that made you put down the other ones.
The full Apple Music catalog at your fingertips. A clip editor that hits to the half-second. Album artwork everywhere it ought to be — and silence, never, when it shouldn't.
"Now batting" highlights, progress fill on the active row, auto-stop at the configured clip end.
Drop a lineup screenshot. The app reads names and jersey numbers. Done.
Lifelike voice intros for every player. Generated once, cached forever. No per-player fees.
Persistent bar across every screen. Album art, scrubbable progress, skip controls.
No volume jumps. No dropouts. Plays through phone lock. The speaker just works.
Build different warmup sets for home games, away games, or pre-game stretches. Auto-advance, drag to reorder, swipe to delete. The pre-game runs itself.
Custom colors and logos per team. Share codes for assistant coaches.
Pick your team's accent from a color wheel or twelve presets. Light theme, dark theme, or auto. The app adapts to your colors — not the other way around.
Tactile feedback on every interaction. Smooth spring animation on every sheet, every modal, every drag.
Built in public. Releases ship over the air, so the gap between "added it" and "you have it" is hours, not weeks.
Goes straight to the builder. No team, no ticket queue — just me. I read every message and reply personally.
We built this for ourselves first. Other apps left us fighting the tech instead of coaching the kids — and these kids deserve better. Every player should get their big-league moment, even on a 12U field with chain-link outfield fences. And the parents running scoreboards, the assistant coaches tracking lineups, the older sibling running audio from the dugout — they're the community that makes the season possible. This is for them too.
Open the app, build a team, play a song. No tutorial, no setup screens you have to fight through before first pitch.
Cached roster. Cued audio. Stable Bluetooth. The app is warmed up before you are.
The whole thing is built for one moment — that kid walking up to bat. If we get that right, we got it right.
