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 teaches the class with you.
Spreadsheets to plan it. Seconds Pro to time it. Spotify for the music. Group Fit Studio is all three — your class plan, your interval timer, and your playlist working off the same Start. Already on Seconds Pro? Import your intervals in seconds and pick up where you left off.
- Import from Seconds Pro — your existing intervals, brought straight in
- The plan you built is what runs the class — beginning to end, no improvising
- What's now and what's next, always one glance away
Class Format Builder
Build plans around the way you teach.
Boot Camp. HIIT. Barre. Stations. Whatever your format, 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 formats become the scaffolding for every plan
Live Session
Lead the room, not the clock.
Your plan rides with you to the studio — on iPhone and right onto your wrist. Tap Start and the timer runs your class 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 plan — 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

Every exercise, in depth.
600+ exercises with muscle mapping, equipment tags, and coaching cues — so you can find the right move for the right moment, and teach it with confidence.
