Clarinu — study planning that survives a bad week.
Tell Clarinu when your exams are and what homework is due. It turns that into a day-by-day plan of short study sessions — and quietly rebuilds the plan when you miss one, instead of leaving you to redo the maths yourself.

About Clarinu
Clarinu is a study planning app for high school students, built for iOS and Android. You tell it about your exams and your homework; Clarinu turns them into a day-by-day plan of short study sessions, keeps track of the ones you complete, and rebuilds the plan when you fall behind. It is free, carries no advertising, and works without an account.
How it works
Three steps, and the third is the one that matters.
-
Add what's coming
Subjects, exam dates, how ready you feel, homework and its due date.
-
Get a plan
Clarinu spreads the work across the days you have, in sessions that fit the time you said you can give.
-
Miss a day anyway
The plan rebuilds around what's left. Falling behind stops meaning starting over.
What's in it
-
A plan for today, not a wall of tasks
Each day shows only the sessions you actually have to do.
-
A timer for each session
Start it, finish it, or end early and say how it went — the next plan takes that into account.
-
Progress worth looking at
Streaks, your week at a glance, and what your own history suggests you change.
-
Reminders that stay on your phone
Scheduled by the device itself. Clarinu doesn't use push notifications and never collects a device token.
About your data
You can use Clarinu without an account. In guest mode your exams, homework and sessions stay on your device and are never sent to our servers.
Sign in and your plan syncs so it survives a lost phone. We use two providers: Supabase for accounts and storage, and PostHog for aggregate usage statistics in its EU region. PostHog never receives your email address, your exam topics, or your homework content.
We don't sell your data, and there is no advertising in the app. You can delete your account, and everything attached to it, from inside Settings. The full details are in the Privacy Policy.
