Klemy: Treadmill Workouts
Virtual treadmill: run & walk
Free · In‑App Purchases
Klemy Treadmill runs planned workouts on any treadmill. Start 12-3-30, Hill Walk or Norwegian 4×4 in one tap, or build your own. A Bluetooth FTMS treadmill changes speed and incline for you. On any other, a countdown tells you what to set.
No smart treadmill? Set your speed and the app calculates distance and pace. With FTMS, speed, distance, incline and elevation sync on their own. Start on Apple Watch, iPhone, or both together.
