I really wish there were a better Killer Sudoku app out there...

Ive had this app for some time now -- probably 3 years -- and I use it a lot. It does generate Killer Sudoku puzzles, and I havent found a better iPhone app for that as yet. However, it almost always generates Killer Sudoku puzzles with multiple solutions, which is very frustrating to someone trying to treat it as a logic puzzle rather than a guessing game. Also, the controls are awkward; it would be a lot easier to have two rows of numbers, one for pencil-marks and the other for actual answers, instead of having to constantly toggle back and forth between actual and pencil input mode.
That said, I have not had the problems others have reported. I frequently take a phone call while solving a puzzle, and never lose any of my partially-completed solution. Ive not had it generate a puzzle with no answer.
Finally, I use it so much because I love working Killer Sudoku puzzles, and havent found anything better for the iPhone as yet.
