## What is Saavu?

People feel better after a sauna. They just can't prove it. Existing fitness apps treat sauna as an afterthought, a manual log entry at best. And nobody takes their phone into a sauna anyway. Without data, the habit feels invisible. Without proof, habits fade.

Saavu is a sauna companion that pairs with your Apple Watch. Your Watch goes in with you. Saavu reads what your body does in real time.

Start a session on your phone. Saavu reads your heart rate live from your Apple Watch via HealthKit, guides you through heat, cold, and rest phases, and shows your body's response in real time. Leave the phone outside. Your Watch keeps the session going.

After each session, Saavu shows your heart rate curve, HRV recovery, and a face state, a simple visual that maps to how your body responded. Over time, you'll see your resting heart rate shift, your HRV improve, and your readiness score climb. These are your numbers, compared only to yourself.

Saavu maps saunas, spas, and cold plunge venues near you. Check in when you arrive, and your sessions are linked to the places you visit. Can't find your local? Submit it. The venue database grows with the community.

A quiet calendar on your home screen tracks your consistency. No gamification noise, just an honest record of the days you showed up. Weekly charts show your trend at a glance.

Free users get unlimited session tracking, venue discovery, check-ins, and streak tracking. Saavu Pro unlocks full session history, HRV trend analytics, personalised wellness insights, session sharing, and your wellness score.

Saavu is not a medical app. It does not diagnose or treat any condition. All data is for personal wellness awareness, your body's story, told in your own numbers.

Heat. Cold. Thrive.
