Best iPhone Sudoku app for speed records

I've tried more than a dozen Sudoku apps over the years and this one is by far the best for measuring your true speed. The board can be modified for your specific needs and it isn't cumbersome to flip between pencilling your notes to pencilling your final digit for a cell. It may take a bit of effort to figure out how to make the board perfect for yourself; but honestly, if you have the logical skills to do an extreme board correctly then you have the skills and patience to figure out the wether you want crosshairs on your board. Know what I mean? Have fun!

Great sudoku version!

Grid, numbers, and notes are easy to see. When you are working with a number, all squares containing that number, including in the notes, are highlighted.

Digit first entry allows quick entry of the same number into squares for faster play.

You can enter an incorrect number into a square. If there is already the same number in the line or 9-square, it will highlight in red. Undo will delete numbers in the order you last entered and will replace your notes.

Almost too good to be true!

Or it may be I've just gotten into the style of these puzzles, but I find it's a pretty straightforward progression from attention to detail, through careful analysis, to a race against time to complete the puzzle. This isn't to say it isn't rewarding; just the opposite, rather, AND it saves my arthritic hands from having to use pencil and eraser! Only fault I find is that recently it seems the hard and extreme puzzles made a shift to easier (on the whole), which I consider a mixed blessing.
