Compared to other sudoku apps I’ve used, I’m taking twice as long to complete a puzzle. This is primarily due to the apps poor use of graphics. Almost no use of color to differentiate states; notes are hard to see and notes I’ve entered disappear on their own(!); 3x3 grids within the 9x9 are difficult to distinguish; the tiny completion indicator is useless; and they have this new thing it’s called animation - you might consider taking advantage of that to indicate number completion and puzzle completion. On the good side, you don’t get bombarded with ads if you buy it.
