SudokuU
Read full descriptionHide full description
This SudokuU app will run on the iPhone and iPad. A unique feature is the highlighter that allows the user to highlight specific numbers in the play area for easier identification. This app also allows the exportation of the playing surface to an email for later printing. You can export the puzzle as well as it's solution. This app also includes what I call an X-beam feature that makes the diagonals of the puzzle comply with the rules of Sudoku.

Verdict
The clearest difference is in-app purchases: SudokuU at none against Sudoku Master Challenges's 5. SudokuU also leads on ads (none vs shown). Sudoku Master Challenges's advantage is update cadence (every 3 days vs every 12 months). On price, device support and iOS requirement there is nothing between them.
