Your treadmill, but smarter. Connect via Bluetooth, control speed and incline from your phone, and see every workout as a chart — all for free, no account required. No ads, no videos, no gimmicks — just you and your workout. Go further with Premium: custom programs, heart rate zones, Live Activity, Apple Health sync, and more. CONNECT & CONTROL • Instant Bluetooth pairing — remembers your treadmill for next time • Adjust speed and incline directly from your phone • Export and import workouts and programs — share or back up your data SUPPORTED TREADMILLS • Built for FitShow. • FTMS-compatible treadmills are supported, but FTMS implementations vary by manufacturer. Some allow full control (speed, incline, start, stop) and rich data; some allow data only, with no control over the belt; some restrict third-party apps almost entirely. FTMS itself doesn't relay every metric — steps, for example, aren't part of it. We can't guarantee every FTMS treadmill will work — support depends entirely on what the manufacturer permits over Bluetooth. • Live compatibility list before you buy: https://treadmill-assistant.com/docs/compatibility/ • Treadmill not on the list?
