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.

Thanks a lot for the kind feedback, I really appreciate it. I’m glad you’re liking the Apple Pencil support. I’ll consider your remarks on the readability for the next updates.

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.

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

Developer Response
Hi, thanks for your kind feedback. The setting to disable highlighting is a good idea, I’ll consider it. For showing errors there is an option you can turn on. On the main screen you can tap on the info button in the lower left. There you can enable “Show all errors”. Kind regards Fabian
