About

Savilio is a free website for understanding and practising maths, geometry, logic, science and geography. It is published by MB Apps, a small independent studio that also makes puzzle games for Android.

Savilio offers short quizzes to practise with: a daily challenge that is the same for everyone, a five-question quick quiz and a quiz for each topic. Every answer comes with its explanation, so each question is a chance to learn the method, not just the result.

Numeric answers are automatically recalculated whenever the catalogue is updated. World capitals and regions come from the open dataset mledoze/countries, credited below.

The daily challenge changes at midnight UTC. Your scores stay on your device: there is no account and no leaderboard. Spotted a mistake or have a suggestion? Write to us at mbapps369@gmail.com.
