I previously had a sudoku app, which I really liked, but which now does not now work. This one is is good, except for the controls, which are not intuitive; its also very easy to input the wrong number. The degree of difficulty, is not accurate. I am not a good player, yet am on the Hard group, (level 4) which I consider to be intermediate, at best - many would rate them as easy (beginner or level2). Practically ad free, and only at the beginning, and you can turn off. I am enjoying using it.

Great port of Sudoku! I am not being bombarded with ads or fake clicks which is an issue i found on other apps. I really enjoy the helper setting and other personalizations as I am a beginner at Sudoku and it's helping me learn much quicker. I'm grateful for the different level challenges too. I only wish there was a setting to turn off (or maybe make invisible) the timer, as I like to play casually not competitively. Though, maybe the setting is there and I've missed it.

Love that you can switch between levels. Love that you can delete unfinished games. It is perfect for me as I'm new to sudoku (I've been living under a rock). It's a non-gamified, elegant app that does exactly what you want it to do. Even the ads aren't overly annoying, but they're annoying enough that I'll upgrade soon.
