The real problem
A pupil knows their grades, but rarely their average before the school report.
In Benin, an average mixes quizzes and tests, then coefficients that change with the grade and the stream. The sum is done in one's head, or not at all. And school apps often ask for an account, a connection and a recent phone.
The tool I built
The school exercise book, brought to life: squared paper, red margin, the average circled in red pen. It runs on a small phone and needs no account and no network.

Under 90 KB on first load. The data stays on the phone.




What changed
Pupils see their average as soon as their grades are in, with the full calculation, instead of waiting for the school report.
The app has been live since October 2026. Pupils are already using it.
