A premium ritual for real home saunas
Made for people with a real sauna at home. A sauna timer and session tracker are included, but the guided ritual is the point.
Built around the flow of a real sauna session
Heat up, cool down, look back later. Your app data is stored on your devices and syncs through your private iCloud account.
Guided rounds with the atmosphere you want
Choose from 17 ambient sound themes mastered for sauna acoustics, including Wood-Fired, or use Silent Mode. Gentle audio cues guide each round, cooling break, and finish without turning the session into a noisy workout timer.
Private session history that stays useful
During the round, stay present. Afterward, review time, heart rate, streaks, achievements, and optional Apple Health / Mindful Minutes sync. Your history is stored on your devices and syncs through your private iCloud account.
Apple Home scenes for lights, fans, and climate
Start a session and let Apple Home (HomeKit) dim lights, run fans, and trigger scenes around the sauna. If you use HomeKit climate sensors, live temperature and humidity can appear during the session too.
More than a sauna timer: a logbook for the room itself
Track stove maintenance, stone replacements, wood treatments, and cleaning schedules in one private journal. Know exactly when your sauna last had attention and when it needs it next.
- Log maintenance dates, work done, and notes
- Keep separate records for multiple sauna profiles
- Private streaks and milestones that stay motivating
- Share session cards only when you want to
Now with cold plunge — your full contrast ritual
Pair the heat with the cold. Start a plunge in one tap, log water temperature, and track your heart-rate recovery — on its own or paired with your sauna rounds.
- Standalone plunges or paired sauna + cold plunge sessions
- Log water temperature and track heart-rate recovery
- Cold plunges on Apple Watch — start, pause, and finish from your wrist
- Plunge timer stays on the Lock Screen and Dynamic Island
Keep the phone outside
Start, pause, resume, and end sauna sessions right from your wrist. See heart rate live during every round, and check climate readings from connected HomeKit sensors without walking out.
- Full session control from Apple Watch
- Live heart rate and round progress on your wrist
- Start and track cold plunges from your wrist too
- Optional temperature and humidity from HomeKit climate sensors
- Sessions sync back to iPhone automatically

Sauna Assistant App
No account or sign-up is required. Sauna Assistant does not ask for your name, email address, or a password to use the app.
Your session history, notes, settings, and maintenance records are stored locally on your devices. When iCloud is enabled for Sauna Assistant, this app data also syncs through your private iCloud account so it can stay up to date across your Apple devices.
We do not receive or access your session data. Sauna Assistant does not operate a server for this data. No app analytics or tracking software is included, and the app does not show ads.

Questions from home sauna owners
What people usually want to know before they buy once and keep it.
Does it control my sauna lights automatically?
Yes. Sauna Assistant integrates with Apple Home (HomeKit) to create fully automated experiences. Set up scenes for your smart lights, fans, and other devices once. Then every session automatically adjusts your environment without touching a switch. Different lighting for sauna rounds vs. cool-down periods—it's like having your own spa attendant.
Is this a subscription or one-time purchase?
$19.99. Once. Forever. No recurring fees, no hidden costs. Buy once and enjoy all current and future features forever. We believe in simple, honest pricing.
Is my data private and secure?
Yes. Your sessions are yours alone. Sauna Assistant requires no account. Your session history, streaks, and settings are stored on your devices and sync through your private iCloud account. The app has no developer analytics or tracking.
What if I want to use my own music?
Sauna Assistant includes 17 ambient sound themes mastered for sauna acoustics, and we add new themes with app updates. We also offer Silent Mode so you can bring your own music or enjoy peaceful quiet. You still get intelligent round timing, smart home controls, and session tracking—just without our audio themes.
Do I need to bring my phone into the sauna?
No. Your phone connects to your sauna's multimedia system (Bluetooth/AirPlay) and controls HomeKit lights wirelessly, so it can conveniently stay outside. With the Apple Watch companion, you can start, pause, resume, and end sessions — and monitor your heart rate — directly from your wrist. You can also control your session via Live Activities on your Mac or iPad.
Can I track cold plunges and contrast therapy?
Yes. Start a cold plunge in one tap, log the water temperature, and track your heart-rate recovery. Run plunges on their own or pair them with sauna rounds for a full contrast ritual. Cold plunges work on Apple Watch too, and the plunge timer stays on your Lock Screen and Dynamic Island while the app is closed.
