Many good features make this easier to do than if you had a printed puzzle and were using pencil. One of the best is that an entered number lights red if it's the wrong number. This lets you correct yourself before one error generates others. Another is the ability to quickly highlight all the cells in the puzzle that contain a given number. Of course other apps may have these same features.8

I love a no-nonsense app that doesn't have ads and doesn't collect my personal information either- and for a very reasonable price! I would very happily update to 5 stars if I could select a number, and have the rest of that same number in the puzzle highlighted. I find it harder on my eyes to scan the puzzle on a screen than on paper, and it gives me a bit of a headache. If that feature were to be added, having it be an optional feature would be ideal!

Not bad, but for a "premium" app it certainly lacks a lot of QoL features. For example, if I make notes, and then write a number, related notes are not removed. Or making notes could be easier by select number, make it a note and then click all fields where you want to put note. Option to higlight all same numbers so you can see them easier.
