Turn heat and cold into a ritual.
Sauna Assistant guides your home sauna from first round to final rest. Pick a ritual, press start, and let calm audio cues carry you through heat, cold and quiet. Your iPhone stays outside the sauna and plays through your sauna's speakers.
NEW: EVERY SAUNA COUNTS
- Log a sauna or cold plunge you had without the timer, at a friend's, a spa or before you had the app, and it counts toward your history and streaks
- Add date, length, rounds, temperature, humidity, plunges and a note, or just say "Log a sauna session" to Siri
- The free web timer at sauna-assistant.com can send a finished session straight to your history
- A short, optional setup names your sauna, connects only what's in it (Apple Home, a Saunum heater, a speaker) and has your first ritual waiting on Home
- On iPhone Duo, the session clock gets its own side of the screen, and History, Home and Settings spread into two columns
GUIDED RITUALS
- Follow scripted rituals like Finnish Classic (Löyly) and Evening Wind-down: warm-up, rounds, rests, plunges and a closing ceremony
- Hands-free mode moves you from round to rest to plunge on its own
- Adjust the next round, skip a plunge or wrap up early without losing your flow
- Gentle hydration nudges during rests
SAUNA & COLD PLUNGE SESSIONS
- Build your own sessions with custom rounds and countdowns
- Add cold plunges between rounds, or start a standalone plunge
- Track plunge time, water temperature, humidity and room temperature
- Follow along on the Lock Screen and Dynamic Island with Live Activities
- Widgets: Quick Start a sauna or plunge, see this week's sessions and streak, or repeat your last ritual in one tap
- Control sessions with Siri, Bluetooth headphones or Apple Watch
IMMERSIVE SOUNDSCAPES
- 17 ambient themes including Wood-Fired, Ocean, Zen, Forest Walk, Thunderstorm and Winter
- Round-specific audio cues and wellness tips during rests
- Switch themes mid-session, or go silent when you want complete focus
- Make your own theme: your own ambience and round sounds, any length, plus a gradient, a symbol and a tip
- Share a theme as a file, and a friend can preview it and open it straight into their app
- Custom themes sync to your iPhone and Apple Watch through iCloud
APPLE HOME & HEATERS
- Trigger your Apple Home scenes when a session starts, pauses, resumes or ends
- Monitor live temperature and humidity from compatible HomeKit sensors
- Connect a Saunum LEIL heater over Wi-Fi to see cabin temperature and heater status
- Log min, max and average conditions for every round
HEART RATE & HEALTH
- See live heart rate and zones during sauna and plunge sessions with Apple Watch
- Save sessions to Apple Health as Mindful Minutes
- Plunges are saved as separate workouts, so you can see how your heart rate responds to cold on its own
PROGRESS & ACHIEVEMENTS
- Session history with statistics and trends across months
- A 12-week activity heatmap and streaks
- Achievements for consistency, endurance and variety
- Share session cards with friends
BUILT FOR SAUNA OWNERS

- Sessions and maintenance side by side on one timeline
PRIVATE BY DESIGN
- Pay once, own it forever. No subscription, no in-app purchases
- No account required
- Your history syncs privately through your own iCloud
Sauna Assistant is for people who want more than a timer: a calmer, more intentional sauna and cold-plunge ritual.
