Siyavula

Adaptive maths, physics and chemistry practice cited directly by South African high schools for Matric exam prep — instant marking, step-by-step solutions, past papers. The Play Store listing for this app is itself a wrapped version of the same site rather than a separately built native app, so there's no separate download to skip — the browser version is simply the product. Open siyavula.com and add it to the home screen for exam season.
