Kitdoku

A simple Sudoku app for my wife. No ads between puzzles, no pop-ups, and no timers ticking in the corner. You pay once, and the app leaves you alone. Multiple modes for every Sudoku player from campaign, to quick play, to a puzzle a day. You can pick from easy, medium, or hard boards and play it your way. The numbers are large and easy to read, even when your eyes are tired or your glasses are somewhere else. Stuck in the middle of a game? Tap Hint. The app points at a cell and tells you why the answer goes there, in plain words. Or turn on mistake checking to see wrong numbers right away. Works without internet on a plane, train, or wherever you are. Kitdoku never needs to connect to anything and your progress stays on your phone. New phone? The app also backs up to your iCloud. There is no account required, no email, and no tracking. Made for iPhone and iPad.
