More than a timer. Group Fit Studio is the all-in-one class planner and interval timer built for group fitness instructors. Design how your class flows, fill it with moves from a catalog of 900+ exercises, then press play to teach with your plan and timer working together. Whether you teach HIIT, Tabata, circuits, bootcamp, strength, yoga, Pilates, or barre, Group Fit Studio adapts to your format. Plan, timer, and music live in one app, and the class you build is exactly what the timer runs. GET STARTED IN MINUTES Pick a ready-made starter class and make it yours, or start from a blank page. Rehearse it as a live session before you teach it for real. ONE CLASS, ONE PLACE Each class gets one workspace: timed blocks, group intervals, and station rotations, plus warm-up and cool-down. Set the structure once, then refresh the moves week after week. PRESS PLAY Tap Start and the timer runs your class: work and rest countdowns, auto-advance, and skip forward or back on the fly. Pair an Apple Music playlist and it ducks under the countdown beeps. WEAR IT ON YOUR WRIST Start and run a class from your Apple Watch without picking up your iPhone. The Watch shows the move you're on and what's next, controls the session from your wrist, and records the class as a workout in Health.
