Features
Hydration reminders
A depleting countdown ring shows time until your next reminder. Notifications fire in the background on a configurable interval, respect an active-hours window, and let you log water, coffee, or tea with one tap — even from the notification itself.
Sugar tracking
One-tap logging for typical sugary drinks with realistic defaults, plus a gentle nudge once today's total passes the WHO's recommended daily free-sugar guideline — informational only.
Alcohol tracking
A rough BAC countdown estimated from the Widmark formula using your sex, age, and weight, one-tap logging for typical drinks, and a permanent reminder that alcohol is a drug — with links to support resources. Not medical advice, never for judging fitness to drive.
Streaks & achievements
Tracks your current and best hydration streak, unlocks achievements for milestones, and lets you compare streaks with friends by trading a short text code — entirely local, no accounts, nothing synced unless you share it yourself.
Private by design
Everything is stored on-device with shared_preferences. An optional one-way sync mirrors logged water to Google Health Connect — nothing is ever read back, and no data reaches a server, because there isn't one.
