About Floe · Sauna & Cold Plunge
Heat, then cold — the oldest recovery ritual, finally tracked properly. Floe times your sauna rounds and your cold plunge, keeps your weekly streak and writes every session to Apple Health as a workout. No account, no feed, no subscription required: pay once and it's yours. YOUR PHONE STAYS OUTSIDE Start the timer, leave the phone on the bench. Floe keeps time on the Lock Screen and in the Dynamic Island, nudges you when a round ends, and picks up exactly where it was if the app gets closed. SAUNA • Rounds, heat and break length — breaks up to 45 minutes, and „Next round now" when you're ready earlier • Live Activity with round progress and temperature • Contrast session: save the sauna and go straight into the plunge COLD PLUNGE • Count-up timer with your target and a gentle nudge when you reach it • Temperature in °C or °F WEEKLY PROTOCOL • Søberg (57 min heat · 11 min cold), Huberman, Laukkanen, Wim Hof — or your own weekly minutes • Streaks by week, visits per week and month, awards for milestones • Log past sessions from the home screen PRIVATE BY DESIGN • Everything stays on your device — no account, no cloud, no tracking • Apple Health: sessions written as sauna / cold plunge workouts • Home Screen widget and share cards for your best sessions Floe is a one-time purchase or an auto-renewing subscription.
