SpringChange is a planning tool for Reformer Pilates instructors. Build your class ahead of time, every move, spring setting, and duration, then let the app run the timing while you teach. BUILD A MOVES LIBRARY Save each exercise the way you actually teach it: spring load, teaching cues, layers and variations, and modifications for clients who need an alternative. Tag moves so you can find them fast when you're planning. PLAN CLASSES IN BLOCKS Group moves into blocks, warm-up, footwork, arms, a left side and a right side. Drag to reorder. Duplicate a block to mirror it for the other side. Give each block a color so transitions are obvious mid-class. RUN THE CLASS A full-screen countdown steps through your routine move by move, with the spring setting and duration for each. Pause, skip, and see what's coming next. Block colors shift as you move through the class, so you always know where you are. ON YOUR WRIST Send a routine to your Apple Watch and the countdown runs there instead. Your watch taps you on the wrist at every move change, so you can leave your phone off to the side. TRACK YOUR TEACHING Set up your weekly schedule, and log what you taught and when. Each routine keeps its own history, so you can see when you last used it. SHARE WITH OTHER INSTRUCTORS Send a routine to another instructor. They can view it and save their own copy to adapt, your original stays untouched. MUSIC Attach a Spotify playlist to a routine so the right music is one tap away when class starts. — SUBSCRIPTION New accounts get a 7-day free trial with full access, no payment details needed.
