Love this app! – Sudoku SE Review
4 levels - from easy to expert.
It keeps track of your best time, for each level, & your average time.
Challenging to try to beat your best time.
It has notes - to put in possible numbers.
I can start a game, pause it, & return to it (resume) whenever I’m standing in line somewhere.
