Broad treadmill compatibility
TreadSimple uses the Bluetooth FTMS standard supported by many modern treadmills, so it is not tied to a single equipment brand.
Compatibility depends on the treadmill model and its FTMS implementation.
Indoor runs. Uncomplicated.
Your treadmill,
simply connected.
Connect your iPhone to a compatible treadmill and heart-rate monitor. See the numbers that matter, record your run, and take your workout with you.
