Allows you to solve the puzzle yourself. Gives helpful hints without doing the work for you. Excellent!!

Latest update is annoying

You have to log in with your Apple ID every day if you have paid for no ads. The messaging system doesn’t work. Very frustrating

Best way to do Sudokus

Astraware is responsible for my addiction to Sodukos. They have the most user friendly interface I have used. The pencil marks are simple to use, especially on the iPad where each number has an assigned location. I can very quickly assess the number status by observing the pencil mark patterns. I also love the ability to be timed and compare my times with other players. It gives me an opportunity to evaluate how I am doing.
I started using Astraware Sudoku years ago on my Palm Pilot. This was the first app I looked for when I received my iPad years ago.
