Built for Game Day

The Game Day screen is where Roll Call earns its keep. The current player, on-deck player, audio mode, and lineup controls stay right where you need them — so you’re not digging through notes, playlists, or group texts between batters.

Every Player Gets Their Moment

Every player deserves a walk-up moment, even if setup is not perfect yet. Add songs, announcer intros, photos, numbers, team colors, imported audio, or crowd reaction clips — as much or as little as you like.

If a full cue is not ready, Roll Call can fall back to an intro, a song, or a built-in cheer, so Game Day always keeps moving.

Softball, Baseball, and More

Roll Call was built around the rhythm of softball and baseball: roster, lineup, on deck, now batting, and cue the music.

But it is flexible enough for other sports, school events, rec teams, ceremonies, and group introductions — anywhere you want quick, personal audio cues.

Private. Simple. Yours.

Roll Call does not require an account, public profile, or team page. Your teams live on your device. When you want to back up or share a team manually, export a .rollcall package and import it on another device.

Bring the walk-up moment to your next game.

Set up your team, assign a few cues, and give every player their moment.
