Amplify everything with hydration
Hydration is the baseline your mind and body performance runs on
A performance lever most people never touch. Raise the baseline — body and mind — by getting hydration right.
Continue to be intentional about the things that matter. We'll help with drinking water
You already decided to take care of yourself. Know the body, read the signals, act on information. Hydration is the last piece.
Personalised targets for sport
Get a hydration target built around your sport, your movement, and your day. Connect Strava and Apple Health — every run, ride, and rest day shapes your number automatically.
Get clarity on what's behind it. Weather, body weight, intensity, duration — every factor is broken down so you can see exactly why your target is what it is. Track consumption, compare weekdays to weekends, and see what drove it up or pulled it back.
Get reminded to rehydrate after a session, and get the accountability to stay consistent day to day. Start with a free 7-day trial.
Smart post-exercise reminders
After a run or ride, it tells you exactly how much to replace and when — backed by peer-reviewed exercise physiology. Reminders arrive when they're useful and stay quiet when they're not.
The smart bottle with invisible tracking. In the lab.
