Sugarizer

Sugarizer brings the Sugar learning platform to your phone or tablet. Sugar was built for the One Laptop per Child project and has been used by more than 2 million children. The home screen is a set of activities, and each activity is a small program for drawing, writing, maths, games or making things.

The activities are packed inside the app, so you do not need a website to use them. There are tools for drawing and writing, a calculator, chess, memory games, mazes and puzzles, a clock and a stopwatch, and block-based programming with Turtle Blocks and Scratch. Whatever a child makes is kept in a Journal, the same way it works on the original Sugar laptops. The app can be switched between several languages, including English, French, Spanish, German, Portuguese, Arabic, Japanese and Polish.

It is a big download, because all the activities are packed inside (the version on F-Droid is about 190 MB). The app runs in landscape orientation only. Working together with other children needs a Sugarizer Server, which a school or a family can run themselves.
