## What is Waterline?

Most water trackers make you subscribe before you can fix yesterday's entry. Waterline doesn't.

Editing any drink, your whole history, Home and Lock Screen widgets, Apple Health and every reminder are free — permanently, not for a trial. Pro is one payment, with no renewal and no account, and it adds depth rather than unlocking the basics.

FREE, ALWAYS
• Log a drink in one tap, as often as you like, forever
• Edit or delete any drink, including the day and time it happened
• Your whole history — every drink you have ever logged
• Home Screen and Lock Screen widgets, with buttons that log without opening the app
• Apple Health — your drinks written out as you log them
• A one-time import of the water already in Apple Health, whole and uncrippled
• Every reminder, on the schedule you set
• Your daily goal, in millilitres or fluid ounces
• Up to 5 containers — add, rename, resize and reorder them
• 5 drinks — water, coffee, tea, sports drink and kombucha — each counting in full
• Habit strength, milestones and your weekly recap
• Undo, and a welcome back after time away — nothing resets
• Dark mode, larger text and VoiceOver labels throughout

PRO, ONE PAYMENT
• Nine vessels in glass, steel and clay, one for each mood
• Drinks of your own, counting for what you decide
• A row for your desk, one for the gym, swapped in a tap
• A goal that moves with your workouts and your climate
• Ninety days of trends, weekends against weekdays, and your habit strength across the whole record
• Your whole record, either way, whenever you ask — and out as a spreadsheet

ON YOUR WRIST, AND WHEREVER ELSE YOU ARE
An Apple Watch app with its own log and a complication. Three Siri phrases and a Shortcuts action. A Control Center tile you can bind to the Action Button. An optional Live Activity that shows today's progress on the Lock Screen and ends at your bedtime.

PRIVATE BECAUSE OF HOW IT IS BUILT
No account, no sign-up, no server. Your drinks stay on your device and in your own iCloud, so they reach your other devices without ever passing through anything of ours. No analytics, no crash reporting, no advertising, and no third-party code of any kind. Settings has a button that deletes everything, from the device and from iCloud.

Waterline is not a medical device and does not provide medical advice.

Pro is a single purchase, restored free on every device you own, for as long as you own them.
