Cup8 is a minimal water tracker for people who want to log a drink in seconds. Open the app, tap a quick amount, see today's progress, and move on. No account, no server, no AI hydration score, no social pressure.
What it does
A quieter way to keep up with water
Fast daily logging
Use quick-add buttons, custom milliliter entry, undo after adding, and a clear progress ring for today's goal.
History and gentle stats
Review entries by day, edit past entries, see a 7-day trend, current streak, and a small monthly summary.
Local first, Health optional
Records are stored locally with SwiftData. Apple Health writing is optional and only runs after you enable it.
Dojoism note
