Plan at home.
Press play in class.

More than a timer app. Plan your class, press play, and Group Fit Studio runs the timer, cues what's next on your wrist, and plays your music — so all you have to do is teach.

Built for freestyle instructors

A timer counts. This app teaches the class with you.

Most instructors juggle three apps: a spreadsheet for the plan, a timer for the intervals, a music app for the playlist. Group Fit Studio brings all three together.

Every round, set, rest, and transition is set before you walk in
The class you built is what runs the room — beginning to end, no improvising
What's now and what's next, always one glance away

Class Builder

Build classes around the way you teach.

Boot Camp. HIIT. Barre. Stations. Whatever you teach, design the structure once — timed blocks, groups, stations — and reuse it every week.

Drag-to-reorder blocks with live duration estimates
Three block types cover every group fitness format
Saved classes become the starting point for every week

Live Session

Lead the room, not the clock.

Your class rides with you to the studio — on iPhone and right onto your wrist. Tap Start and the timer runs it block by block, so your focus stays on the people in front of you.

High-contrast full-screen timer, readable at a distance
Automatic transitions through blocks and stations
Pause, resume, or skip without losing your place
Glance at your Apple Watch for the next exercise — no looking down at a phone
Pair an Apple Music playlist with your class — it auto-plays when you tap Start
Tap Start to run the class as a tracked Apple Watch workout — pick the type (HIIT, Functional Strength, and more) and see your summary when class wraps
