Score

Abitur planning without the 2009 Excel vibes or mandatory accounts.

Context

A local-first iOS grade tracker that syncs via iCloud—no backend, no sign-up, just your data encrypted and under your control. It calculates your Abitur score correctly, which is more than I managed for weeks.

Why I built it

I wanted a grade tracker that didn’t look like a spreadsheet or demand an account just to log a bad math grade. Turns out the real challenge was the Abitur formula—42 courses, 40 counted, two doubled, divide by 48, multiply by 40. Took me longer to debug than the iCloud sync, and this means something.
