Water Tracker for Dummies

Features
Read full description

Water Tracker for Dummies is a fast, offline water routine tracker for iPhone and iPad. Tap a drink size, log a custom amount, choose a catalog beverage, or refill a named bottle from Bottle Bench, then watch today's total, goal progress, weekly history, and long-term trends update instantly. Version 1.6 adds Bottle Bench, a carry-bottle ledger unique to this app. You name the vessels you actually use, set each measured capacity and fill mark, and tap Refill to log that pour. It is not a generic size grid and not a cloned worksheet from another app. The app also includes Hydration Rhythm for timing consistency, Routine Coach for pace, past-day entry, a catch-up advisor, on-device reminders, a goal calculator with transparent sources, beverage hydration index estimates, charts, all-time insights, color notes for personal journaling, export, import, and oz/mL/cups display modes. No account, no ads, no analytics, no cloud sync. Records stay on the device unless the user exports them. Water Tracker for Dummies provides general wellness information only. It does not diagnose, treat, monitor, or replace qualified guidance.
