The effortless water tracking app
One tap to stay hydrated
Log a cup or bottle in a single tap, or ask Siri and tap the Lock Screen widget. Watch your progress ring fill toward a daily goal that grows on your active days. See your history, hit your goal, and enjoy a little celebration each time. Works with Apple Watch and Apple Health.
Quick-log water, watch your goal fill up
No clunky number pads. Tap a preset — a cup, a bottle, a big bottle — and your progress ring updates instantly toward today's goal, with a little celebration when you reach it.
One-tap presets
Cup, bottle and big bottle presets sit in a quick-log popover, so a typical drink is logged with a single tap.
Customizable amounts
Set each preset to your own cup and bottle sizes in ml or oz, so the numbers always match what you actually drink.
Daily goal & progress ring
A clear ring and bar show how much you've had versus your daily goal — see at a glance whether you're on track.
Celebration animation
A satisfying celebration plays when you log a drink and when you finally hit your goal — small reward, real habit.
History & trends
Browse past days to see how consistent your hydration has been, and spot the days you fell short.
Easy corrections
Logged one too many? Adjust or remove an entry in a tap so your daily total always reflects reality.
Log from your wrist, your Lock Screen, or just your voice
The fastest way to log is the one you don't have to open the app for. Use Siri, tap the Lock Screen widget, or log from Apple Watch — and let your goal rise with your activity.
Log with Siri
Say "log a glass of water" and the LogWaterIntent records it for you — hands-free, and it works in Shortcuts too.
Lock Screen WaterWidget
Add the WaterWidget to your Lock Screen and quick-log a drink with one tap, without unlocking your phone.
Goal grows with activity
Connect Apple Health and your daily water goal automatically increases on days when you've been more active.
Apple Watch sync
Log and check your progress straight from your wrist; entries stay in sync with your iPhone.
One goal, every device
Your daily goal and progress are the same whether you're on iPhone, the widget or the Watch — no double counting.
Lightweight & private
Quick-log runs locally on your device with no AI required — fast, battery-friendly and free.
About water tracking

No. There is no automatic sensing of drinking — logging is always one tap, via Siri, or from the Lock Screen widget. The only thing that adjusts automatically is your daily goal, which can increase based on your activity level read from Apple Health.

Yes. Your water logs sync to Apple Watch so you can log and check progress from your wrist, and connecting Apple Health lets your daily goal increase automatically on more active days.
