Frequently asked questions

Both (Min and Max) heart rate limits are fixed by design. RscMe uses the widely respected calculation for the maximum heart rate: HRmax = 208 − (0.7 × age). This formula is based on the clinical study from Tanaka, Monahan and Seals published in Journal of the American College of Cardiology (Vol. 37, Issue 1) in January 2001. The low end is also fixed, at 40.

The RscMe app is compatible with all models of Apple Watch.

  1. Go to your iPhone’s Settings and disable Touch ID or Face ID for iPhone Unlock.
  2. Set the “Require Passcode” option to “After 4 hours” (recommended) or turn Passcode off.

RscMe iPhone settings

The RscMe app reads the heart rate data from your iPhone's Health app. So if your Fitbit is connected and heart rate data synchronised with iPhone's Health, it will work.
