A spirit cat who keeps you drinking water
Mewlet is a hydration companion for iPhone. A digital spirit cat sits beside today’s water, asks for a glass when the day falls behind, and lives in the Dynamic Island with your progress beside it.
One-time purchase — no subscriptions, no in-app purchases. iPhone with iOS 17+; the Dynamic Island needs an iPhone 14 Pro or newer.
One cat, four moods
The cat is a mascot, not an assistant — it never chats and can’t be asked questions. It simply answers to the numbers you set.
On track
Sits and blinks, keeping you company.
Goal done
Curls up happy once you reach your goal.
Drinks with you
Has a sip whenever you log a glass.
Off hours
Sleeps outside the hours you set.
Small on purpose
One page, three things on it, and everything else tucked away. No account, no setup, nothing to learn.
One tap to log
Three buttons whose sizes you choose (100 / 200 / 300 ml by default), a menu of other sizes, a custom stepper — and Undo for the glass you logged by mistake.
The cat answers to the numbers
It sits when you’re on pace, drinks when you log, and lets you know when the day falls behind — but only once you’re more than one glass behind your own schedule.
In the Dynamic Island
The cat on one side, today’s water on the other. Long-press to expand it for the progress bar, the amounts, quick-log buttons and undo — without opening Mewlet.
600 / 2,000 ml30%Reminders you set
Local notifications on your own schedule — nothing arrives from a server. Give your cat its own words and the reminders speak in its voice.
Widgets & Lock Screen
A small and a medium Home Screen widget, plus circular, rectangular and inline Lock Screen accessories — each with one-tap logging that works with the app closed.
Your own companion
Choose a photo from your library, name it, and write its reminder line. The picture never leaves your phone — the island and widgets draw a tiny palette copy of it.
Mewlet has no backend, no account, no sync and no analytics, and it links no third-party SDK. It makes no network requests at all. Your water log is one file on your phone — nowhere else — and Delete All Data removes it in one tap.
Meet your cat
Mewlet is coming to the App Store. A reminder helper, not a medical device — it repeats the goal you set and advises nothing.
