Disappointed

Of course, you can enter your own pencil marks. It's the first button on the right in the top row There's also a built-in help feature (the info button).
Won’t work
Response from developer
I don't know why you wanted to be reimbursed for your $0.99 investment. I guess it's the crash problem when you create a new random puzzle on latest versions of iOS. This problem is corrected in the current version (1.4). I agree with you that an app that crashes systematically should be reimbursed but I'm not responsible of Apple's refund policies.
Total bust

Sudoktor worked without a hitch with earlier versions of iOS. But for at least a year now, it's been crashing when you want to create a new random puzzle. This is fixed in version 1.4.
Non functioning app

It is strange. I have never seen Sudoktor freeze or crash. Could you send me a screenshot of when this happens?
Different in a good way
I like that Sudoktor will calculate and continuously update possible candidates for me, I can do this for myself but honestly it's a tedious unchallenging part of solving a puzzle.
One element of Sudoktor which as far as I am aware is unique, is the user interface it uses when entering either your guess or a pencil mark. You select the cell you want to work with and the display pops up a larger square containing the values that you may choose. The really clever part of this is that it represents pencil marks as small digits and guesses as large digits. This feature has once and for all ended the problem of accidentally entering a guess instead of a pencil mark because it is obvious which you are about to do.
I also like very much the ability to import and export puzzles, other apps have this but Sudoktor seems to go one step further and allow many options for import and export format.
The analysis feature is interesting, it's not just on or off, you can select the type(s) of analysis that you want the program to use. I find ths helpful as a learning aid when stuck. The display shows exactly what your next move should be and more importantly shows you why. You can see the explanation on the actual puzzle you are working on.
All in all Sudoktor is a step ahead of any other Sudoku app I have seen.

I should have thanked you sooner for this review.
