Sauna season is here. Build your own sauna soundtrack in v27. One price, no subscription.
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.

Sauna Assistant is for people who want more than a timer: a calmer, more intentional sauna and cold-plunge ritual.

Make the sauna yours. Build your own theme with your own sounds, colors and symbol, and share it with a friend.
NEW
- Custom themes: give your theme a name and a tip, pick a gradient and a symbol, then add your own ambience and round sounds. iCloud carries it to your iPhone and Apple Watch.
- Share a theme: export it as a file and send it to a friend. They open it and it goes straight into their app.
- Redesigned widgets: Quick Start begins a sauna or plunge from the Home Screen and counts down live mid-round. This Week keeps your sessions and streak on the Lock Screen. Last Session
brings the same ritual back with one tap.
- Saunum LEIL heater: connect it over Wi-Fi to see cabin temperature and heater status. Tap Find Heater on Network and the app finds it for you.
IMPROVED
- New achievement badges, drawn in the style of the app icon.
- The 12-week streak now shows how many sessions each week held.
- iPhone and Apple Watch stay in step more reliably. If the Watch stops responding during a session, the session screen tells you.
- Built for iOS 27.
