FAQ
How is maximum heart rate estimated?
You choose a published formula (Fox, Tanaka, Gellish, or NES). The app applies it to the age you enter. Each formula is an estimate for the general population—not a personal medical measurement.
Is my data uploaded to your servers?
No account is required. Inputs and saved history are stored on your device. We do not run in-app cloud sync for this app.
Can I use this for medical decisions?
No. Results are for general fitness and training reference only and are not medical or clinical advice.
