Hi PH — I'm the developer. Built it after one too many mornings wondering whether last night's drinks had cleared. Log each drink as you go; the app personalizes the Widmark r via Watson's total-body-water formula, shows a plain Widmark estimate side by side, and keeps counting in the notification shade after you close it. No account, no server — everything stays on the device. Android only for now (iOS is next). Happy to answer anything about the formula — the calculation core is open source in the repo linked above. It's a reference estimate, not a medical device; please never use it to decide whether to drive.
