Koa now lives on your phone (plus 6 new goodies in the shop)

Koa is on your phone: the Pinkoa study timer app with streaks, to-do list and dress-up Koa

Big little update: Koa can now live on your phone. Open pinkoa.com, tap "Add to home screen" and Koa gets its own pink icon next to your other apps. It opens full screen, straight to the study timer, with no app store, no download and no account.

What's new on the timer

🔥 Study streak: finish at least one pomodoro a day and watch your streak grow. Your best streak is saved too.
📊 Your last 7 days: a little bar chart of how many rounds you did each day.
✅ Study to-do list: jot down what you need to get through ("Chapter 4 flashcards") and tick it off between rounds.
👋 Welcome back: when you come back, Koa greets you with your current streak.
🎀 Dress up Koa: glasses, a bow, headphones, a scarf and more, plus new fur colours and cosy scenes like a rainy window or a night sky. The more pomodoros you finish, the more you unlock (the crown takes 50!).

Why we keep your data on your device

Everything above is saved only in your own browser, on your own phone or laptop. We think that's the nicest way to do it:

Private: your to-dos and study habits never leave your device. We don't see them and we don't store them.
No sign-up: no email, no password, no account to forget. Just open it and study.
Fast: nothing has to load from a server, so it's there the moment you open it.

Good to know: because it lives in your browser, your streak stays on that one device. If you clear your browser data, Koa starts fresh.

How to add Koa to your home screen

iPhone: open pinkoa.com in Safari, tap the Share button, then "Add to Home Screen".
Android: open pinkoa.com in Chrome and tap "Add to home screen" on the Koa app card (or use the browser menu ⋮ → "Install app").
