A performance lever most people never touch. Raise the baseline — body and mind — by getting hydration right.
You already decided to take care of yourself. Know the body, read the signals, act on information. Hydration is the last piece.
The B bottle lid means you never log a thing. How much you've drunk, monitored in the background. Nothing to do.
Open the app on the days you want more depth. It knows when to show up and when to stay quiet.
Or touch the light ring to check in simply, without needing your phone.
Optional Upgrade
Get insights, personalisation, patterns, trends and learnings, on the iOS App. Also unlocks additional hardware features.
Get ongoing clarity over something that matters. Everything you care about got smarter. Your training. Your sleep. Your recovery. Hydration never caught up. Until now.
Accountability is here.
Calculated from your run, your ride, your environment, your body. Smart reminders tell you exactly how much to replace, backed by peer-reviewed research in exercise physiology and sports nutrition.
Weekly patterns surface over time. Weekday versus weekend. What shifts, what holds. Keep knowing. Keep refining.
For mastery, to get better or just trying out. Configure the tech to how hydration fits in your future lifestyle, to the inputs you want. The goal, just the right information.
