ColdPlungeAutoTimer

Official launch! autoColdPlungeTimer uses your Apple Watch to detect water temperature and start your timer automatically - no tapping required.

autoColdPlungeTimer is the hands-free cold plunge companion built for Apple Watch Ultra models.

Most timer apps make you fumble with buttons the moment you need to focus. autoColdPlungeTimer is different. Simply set your temperature threshold in Settings — when your Apple Watch detects the water has dropped below it, your session timer starts automatically. Get in, breathe, and let the app do the rest.

Features • Auto-Start Timer — session begins the moment water hits your temperature threshold, detected by your Apple Watch • Customizable Breathing Exercises — guided pre-plunge breathwork to prepare your body and calm your mind • Progress Tracking — review your session history, build streaks, and hit your goals • Temperature Log — your Apple Watch logs water temp every session so you can track trends over time • Streaks & Goals — set weekly targets and stay consistent

Cold therapy is about focus and discipline. autoColdPlungeTimer keeps the tech out of your way so you can stay in yours.
