Ounce
Daily Hydration Log
Track your daily water and drink intake right from your wrist. No iPhone required, no subscription, no account — just clean, private hydration tracking built for Apple Watch.
Everything you need. Nothing you don't.
Built Watch-first, Ounce keeps your daily hydration goal front and centre — right on your wrist.
Watch-first logging
Log a drink in one tap directly from your Apple Watch. No need to reach for your phone. Ounce lives where you need it most.
Always-on complication
Add Ounce to any watch face. Your daily progress ring stays visible at a glance, so you always know where you stand.
Smart wrist reminders
Set a reminder interval and active hours so Ounce nudges you during the day — and never during the night.
Hydration coefficients
Coffee, tea, and juice count — but not equally. Ounce adjusts each drink's contribution so your total reflects true hydration.
Daily history & streaks
Review your intake day by day and build a streak. Consistency is what makes hydration a habit, not a chore.
Apple Health sync
Every drink you log is written to Apple Health automatically. One permission, clearly explained, and your data stays in your ecosystem.
Track what you actually drink
Ounce counts every beverage toward your daily goal — with smart hydration adjustments built in.
Private by design. Not by policy.
Your hydration data is yours. Ounce never sends it anywhere — not to a server, not to an ad network, not to us.
