About
The GCSE revision app I wish I’d had.
Biro marks your answers the way an examiner would, then shows you what you missed. The order of topics rebuilds itself around whatever you keep dropping marks on, rather than marching everyone through the same list.
It pays you back in collectable cards, a binder to fill and a market where you haggle with a bot, and rewards are checked by the server so they can’t be faked. It’s built for under-16s from the ground up: filtered, private, with a named adult for safeguarding.
