Pinkoa

Pinkoa is a free study timer with Koa, a pink koala who studies with you and naps on your breaks. Focus rounds of 25, 50 or 90 minutes (or your own), streaks, rewards, a to-do list, cosy study sounds and outfits for Koa. No account, no ads, works on your phone, in English, German and Finnish. Free printables for students and a free kit for teachers, plus a Classroom Mode for the projector with no logins and no student data.

The name: pinkoa is Finnish and means to run fast, and in student slang, to study hard. Built in about six hours with the AI Claude by a Berlin founder and run in public: every number, including zero sales so far, is live at pinkoa.com/dashboard.
