Fantastic, but a little room for improvement
Sudoku apps and sudoku solvers are a crowded space. This one differentiates by solving step-by-step, so you can learn and practice the techniques it uses. It works great, and has been super helpful to me. There is room for improvement: (1) if a puzzle requires too many steps to solve, the app will crash. Similarly, if it can't go from the entered clues to a final solution, it won't even accept the puzzle. I'd prefer if it took whatever puzzle I gave it without attempting to solve to the end, and then just solved the next step; (2) it would be great if it could enter puzzles from photos, not just the camera; (3) more techniques! Empty rectangles, more fish, etc. For me, chains and subset exclusions are a last resort - I'd like as many "logic only" techniques as possible first; (4) it would be amazing if techniques could be reordered and turned on and off for a particular puzzle; (5) app looks to be out of development. Active updates would be welcome. I would gladly pay for some of these features as in-app purchases. If the app adopted ads, I would delete it.

Extremely difficult to line up camera to solve custom game. Doesn’t explain what each hit does or how it came to its conclusion. Very hard to understand hints.

To JimmyO Software...I can enter a set of numbers but the “DONE” button doesn’t do anything. Any fix for this.?
