Why this exists — Kora

Lagree instructors were running professional classes on generic interval timers built for gym-goers, not teachers. Every move had to be typed in by hand, left/right pairs duplicated manually, transition times calculated on the fly. Worse, the tools were unreliable exactly when it mattered: timers freezing, audio cues dropping, Apple Watch sync glitching — mid-class, in front of paying clients, with a teacher who couldn't just refresh the app. I watched this happen to my partner, a certified instructor, often enough that "just use a better timer app" stopped feeling like an answer.
