SaunaFlow
Hands-Free Sauna & Heart Rate
Free · Designed for iPad. Not verified for macOS.
Your Apple Watch guides sauna, cold plunge, and rest — now with heart-rate tracking that visualizes your “totonoi” moment, plus a Live Activity and a watch complication.
Run your sauna routine without staring at a clock. SaunaFlow guides you through sauna, cold plunge, and rest from your wrist — automatically. Build your routine on iPhone, run it on Apple Watch, and keep refining what works best.
■ START FAST WITH STARTER PRESETS
Get going with starter presets like Standard 90, Quick Set, and Short Cold Plunge. You can edit them on iPhone and they sync to Apple Watch automatically.
■ RUN THE SESSION ON YOUR WRIST
Leave your phone in the locker. Phase changes are announced with haptics, the remaining time is always visible, and Digital Crown controls let you skip or pause quickly.
■ IMPROVE YOUR ROUTINE OVER TIME
Your history helps you review completion rate, best sessions, notes, and score trends. If a session felt right, rerun it or save it as a new preset for next time.
■ DESIGNED FOR REPEAT USE
Favorite and recommended presets surface faster on Watch, so your usual flow is easier to start. The app is built for people who want a repeatable sauna routine, not just a one-off timer.

• Apple Watch now records your heart rate during a session. Your history visualizes the sauna→cold→rest heart-rate curve and marks your calmest “totonoi” moment.
• A Live Activity shows the current phase and time remaining on your iPhone Lock Screen and Dynamic Island.
• A watch face complication starts your next sauna in one tap.
• Refined controls: tap to pause/resume, Digital Crown right to skip, Crown left to add 30s to the current phase.
• The Totonoi score now explains how it’s calculated and factors in heart-rate recovery.
