About the app
Circles is a mobile game-trainer that boosts cognitive abilities in a fun and easy way. Tap numbered circles in the right order (ascending, descending or by remembering their positions), solve math problems, find matching pairs, solve puzzles and catch falling circles. Compete with yourself and climb the leaderboard.
The app is suitable for all ages – from children learning numbers to adults who want to keep their brain sharp. Minimalistic design, no intrusive ads, detailed progress statistics and support for 12 languages.
