Literally the best sudoku app on any platform
Perfect. The interface is clean and easy to use. You are able to enter digits and pencil marks with a single swipe, as opposed to the keyboard method used by most other apps, which makes it far quicker to complete puzzles, and it makes the app easier to use with a single hand/thumb. There is a great variety of puzzles, as well as stat tracking, and the ability to customise your experience with features like automatic pencil mark removal, error checking, etc.
However the biggest selling point of this app is the hint system. This app, unlike any other I have used, uses the hint system to not only help you with your current puzzle, but to teach you to get better at sudoku. There are so many techniques that I would never have known about if it weren't for the hint system in this app. It doesn't just give you the answer, it points out where you should focus, tells you what rule you need to apply, and then if you're still stuck, it tells you how and why to apply that rule. This has actually meant that 99% I no longer need to use hints. This system embodies the saying "give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime".

Nearly perfect
I play killer sudoku mostly, and out of many apps I've tried, I really like playing on this one. The clean interface is delightful to use. Number input is dreamy. The coloured and arrayed pencil marks are really helpful. The hints are a great feature: they are intelligent, the prompts leave you with some thinking to do if you like that, and the direct help means you don't get stuck. I'd like to be able to turn off automatic clearing of matching pencil marks when you enter a number. Help with valid number combinations for cages would be nice although I must admit that not having that forces me to think more. Help with adding cage sums would also be nice. Killer Sudoku + has a good rendition of both these features, and is another nice app, but it does not have arrayed pencil marks or the excellent hints that are given here.

Genius interface
The best user interface I have ever seen in a Sudoku game. The use of color and position to stimulate additional parts of the brain is a great plus
Love this game!
I love love love puzzles and I've never found another game that's so thoroughly challenging and logical in nature. It's a shame it isn't more popular!
Already love it
Looks much more fun and colorful than most sudoku apps and has a good selection of games and an intuitive pencil mark interface
