What the studio makes
Each product is listed against the same five headings: what it is, what it runs on, who it is for, how it is sold and where it stands.
Calm Puzzles
Large-print daily puzzles for iPhone, iPad and Android.
Five kinds of puzzle: Sudoku, Word Search, Nonogram, Binary and Star Battle, with a new daily puzzle of each kind every day. Print is large by default and follows the device text size, with a Large text setting and a High contrast mode. There is no timer unless you turn it on and no limit on mistakes. A hint starts as a nudge, then shows the reasoning, and only then fills in the move. It works offline, with no account and no ads.
