Guide
SaunaMind, simply.
Track the session. See the context. Keep the habit.
1. Start with a session
Choose Sauna, Cold or Training. You can also combine phases in one contrast-style session. Sessions can start open-ended, with timers available when you want structure.
2. Add live heart rate
Pair a Bluetooth chest strap, or a Garmin watch with Broadcast Heart Rate turned on, from More › Devices. If the watch never appears in the scan, pair it once in iPhone Settings › Bluetooth and scan again. Use one heart-rate source at a time. You can still log sessions without one. Wearables may have manufacturer temperature limits and may not be designed for sauna conditions, so use them in the heat at your own discretion and follow the manufacturer’s instructions; see Support for the full note.
3. See your zones
SaunaMind compares your live heart rate with your resting heart rate and places each moment into one of five effort zones: Very Light, Light, Moderate, Hard and Peak. Time in those zones becomes a 0–100 Sauna Load score. No body temperature is measured, estimated or shown. These are wellness estimates to help you understand the session — not clinical measurements. Keep your resting heart rate accurate under More; it sets every zone.
4. Watch your heart rate settle in the cold
Cold sessions track your heart-rate response: where it was when you got in, where it is now, and how far it has settled back toward your resting heart rate, live as a percentage. It is session context, not a medical measurement. Read what your heart actually does in the sauna for the full picture.
5. Keep hydration close
Log water quickly so hydration sits alongside your daily session and recovery view instead of living in a separate app.
6. Use your wearable data
Apple Health supplies your resting heart rate and, with your permission, receives every finished sauna, cold and training session as a workout with its heart-rate curve. Oura and WHOOP feed the readiness view. What is available depends on your device, permissions and app build.
7. Review and share
Progress keeps streaks, weekly minutes and the heart-rate curve of every session. Any workout can be shared as a session card image. SaunaMind is built to be easy to scan rather than overload you with data.
8. Readiness
If you wear an Oura ring or a WHOOP, SaunaMind shows the readiness they already give you next to your resting heart rate, hydration and recent sessions. This is a wellness estimate, not medical advice.
