Sudoku Solver Helper Generator for Android
Very good
A simple app to fill in the candidates and automatically update the candidates for a sodoku you create, but no way to save the data you entered, if you close the app all your work is lost!! The system for entering the data is not easy, it should auto advance to the next cell and should add a 0 for empty cells.
Doesn't generate, you have to input digits manually. Doesn't really help, just gives candidates. Doesn't warn of incorrect entries, only conflicting values. Gives no hints, clues, or tutorial.

I use this app to help me finish grids that I can't finish without using notes. On my small phone my fat fingers mistakes are easy to spot and correct! Very helpful.
