Love this app

I’ve been looking for an easy to use sudoku app and have found it. Was really glad I got to try an online version for free before getting the app. I like that I can “see how I’m doing” before I run into a snag and catch mistakes early on if I choose to. It seems some of the downsides in the other reviews have either been fixed or were user error. The only thing I’d add is to make it easier to erase my penciled in marks. And maybe add in a notes feature. But really, this is a great app and I don’t have any complaints.

Challenging puzzles, easy to use, but eats the battery

I like the competitive option because it allows me to see if I'm improving. There are two significant problems, however. The first is that when playing the game the time of day and remaining battery life, which are otherwise omnipresent, are not shown. The second is that it consumes so much energy that even when my iPad is plugged in, the amount of battery life remaining decreases, which indicates that it is consuming a large amount of energy; an app that only responds to user input, and maintains a timer should utilize very little energy and the fact that it uses a lot makes me wonder what it is actually doing.

Question marks

Great game. It would be even better if you fix the question marks so it will always go to the last position regardless of how many numbers you type. The online version does that automatically, but lately the whole puzzle shifts to the center of the screen as soon as you enter a number. On the iPad it means that you cannot see the number bar anymore. Very frustrating issues with an otherwise fun game. Hope you can fix it.

Also, it would be helpful if the question mark is farther away from the 5. Hard when you use forefinger and thumb.
