Group Fit Studio

More than a timer. Group Fit Studio is the all-in-one class planner and interval timer built for group fitness instructors. Design your class once, then press play to teach from beginning to end.

Whether you teach HIIT, Tabata, circuits, bootcamp, strength, yoga, Pilates, or dance, Group Fit Studio adapts to your format. Most instructors juggle three tools: notes or a spreadsheet to plan, a separate interval timer to run the clock, and music on the side. Group Fit Studio is all three. The plan you build is exactly what the timer runs. No writing on the mirrors, no glancing between apps mid-class.

PLAN YOUR CLASS Create reusable class formats with timed blocks, group intervals, and station rotations. Define the structure once, then build specific plans on top of it. Add exercises from a curated library of over 600 exercises, organized by muscle group and equipment. Set timing per interval and add instructor notes for cues and transitions. Already plan your intervals in another timer app? Import an existing interval timer and we'll scaffold the class format for you. All you have to do is add your exercises and press play.

PRESS PLAY Tap Start on any plan to run it as your real-time guide. A countdown timer tracks each work and rest interval, auto-advances through your plan, and lets you skip forward or back on the fly. Pair an Apple Music playlist with any plan so your music starts when class starts and ducks during the countdown beeps. No more losing your place mid-class.

WEAR IT ON YOUR WRIST The Apple Watch companion mirrors your live session with the current exercise, timer, and progress at a glance. Use the app controls to pause, resume, skip, or end without picking up your phone. Heart rate and active energy are recorded as a workout in the Health app.

BUILD YOUR LIBRARY Browse 600+ exercises, each with step-by-step instructions, primary and secondary muscle targeting, and suggested similar moves to keep your classes fresh. Submit your own exercises to grow the catalog. Submissions are admin-reviewed before going live to other instructors. Save your favorite plans and class formats to reuse and refine over time.
