Wateroo
Drink water. Keep your buddy happy.
You log what you drink, and if you close the day's goal your buddy lights up. Fall behind and it fades, and tells you so.

Every sip counts
for what it's worth.
Tea and coffee are part of your day. The screen shows two numbers: what you poured and what went toward your goal. The catalogue has 34 drinks.
- ×1.15Ayran250 ml → 288 ml
- ×1.10Milk200 ml → 220 ml
- ×1.00Water250 ml → 250 ml
- ×0.85Tea100 ml → 85 ml
- ×0.70Coffee240 ml → 168 ml
The factors come from the app's drink catalogue. Coffee isn't a penalty; it counts for a little less than the same amount of water.

06 · Privacy
Your records stay on your phone.
No account, no ads, no tracking. Two things go out: an approximate location to Apple's weather service if you turn weather on, and an anonymous purchase record to RevenueCat if you buy Pro.
Questions
Is it a tracker or a game?
A tracker first: you log drinks and see today's progress on one screen. The pet is how that number shows up, which makes it harder to ignore.
How is the goal worked out?
Weight, age and activity level give a base. If you turned weather on, a hot and humid day raises it. If weather can't be fetched, Wateroo doesn't guess; the goal is just your own numbers.
Does coffee count?
Yes, for what it's worth. A coffee counts for a little less than the same amount of water. It's part of your day, not a penalty.
Do I need an account?
No. No sign-up, no login, no email.
What if I change phones or delete the app?
Your records live only on your phone. Deleting the app deletes them, and they don't move to a new phone by themselves. There is no cloud backup. Resetting data in Settings clears the local records too, but it does not cancel a subscription.
I bought Pro and it didn't unlock.
Tap Restore purchases in Settings. You need to be signed in with the Apple Account you bought it with.
Which devices and languages?
iPhone on iOS 17 or later. The app is in English and Turkish.
Is the goal medical advice?
No. The daily goal is an estimate for everyday use, not medical advice. If you were given a fluid limit, follow your doctor's advice instead.
