really good potential

this app is designed really well, just missing settings that other apps have, such as "disable highlighting rows/columns/boxes" or "show errors" which i prefer to play on. i'll probably stick with another app unless this one adds settings so you can pick your preferences

Best Sudoku app for iPad

This is by far the best app I’ve tried. It supports Split View which was how i originally found it. Not to mention there are no ads and it merges sudoku and killer sudoku into one app.

Very close to perfect

This is a wonderful app, and the only sudoku app that I’ve been able to find that supports writing in the numbers with the Apple Pencil. To push it over the top, I’d love to see some options in typography and contrast so that it’s a little easier to distinguish rows, columns, and boxes.
