BUILT FOR YOUR WORKFLOW Color-code moves by body part. Select and manage multiple exercises at once. Collapse variation details when you don't need them. Search your routines in seconds. BUILT FOR HOW INSTRUCTORS ACTUALLY WORK — Prep takes minutes, not an hour — Saved moves travel between routines instantly — Run classes on your Apple Watch — One purchase, no subscriptions, updates included THE STORY BEHIND KORA I built this after watching my partner, a Lagree instructor, spend close to an hour every week rebuilding routines in a timer app. Retyping the same moves. Losing sequences. Fighting the tool instead of focusing on the class. Kora was built to fix that. One tool, made specifically for Lagree, Pilates, and Reformer instructors.
