Freezes! – Sudoku Master HD Free Review

This is actually the best suduko app I have found, even better than ones I paid for, but it always freezes, and then you lose all the work you have done. Last thing, it does not get difficult enough, at least not for me, so if you're looking for some REALLY hard ones, then I would either buy the full version, or go somewhere else.
