Peak Hours
A quick reaction check charts when your mind is sharpest, then names your type: morning lark, night owl, or steady all day. No other brain trainer has it.
Seventeen games + puzzles
Memory, focus, reading, timing and spatial games, three skill drills, and classic puzzles like Sudoku, Word Search and Nonogram. One calm app.
Skills you can use

Read your own documents

Private by design
No account, no analytics, no third-party trackers. Your stats never leave your phone. Privacy here isn't a setting you switch on; it's how the app is built.
Yours forever
A single one-time purchase unlocks everything. No recurring charges, ever. Sample several games free, then unlock the rest for good.
Light or dark, your accent colour
