Connect your Bluetooth sensors, generate workouts with AI, and upload to Strava automatically — all without handing over your email or credit card.
What's inside
Pairs with power meters, heart rate monitors, and smart trainers over Bluetooth. Watter remembers your devices and reconnects automatically every ride.
Tell Watter what you want to do — type it out or speak it — and get a structured ERG workout in seconds. Dial it in through a back-and-forth until it's exactly right.
Enable auto-upload and completed rides go to Strava the moment you stop. TCX export is always available if you want to take your data elsewhere.
Power, heart rate, and cadence are stored locally on your phone — not in someone else's cloud. No account required to get started. Just ride.
