This update introduces an all‑new interval training mode and makes your workouts smoother and more reliable: • New HIIT interval training: Choose between "Easy" and "Advanced" paces, with warm‑up, jumping, rest, and stretching — plus a selectable number of rounds and voice guidance to keep you on track. • Keeps counting in the background: Jump counting and voice feedback continue even when you switch apps or lock your screen. • Auto‑save & resume: If the app closes unexpectedly, you can pick up right where you left off the next time you open it. • Various refinements and fixes for a smoother experience. Happy jumping!
