A bit too manual & difficult to maneuver for me

I was a bit miffed at first when I saw there was no way to write notes in the blocks. Then I opened the Options menu and found I could add the question mark button to allow me to do it. If there is another way, I haven't figured it out yet, and trying to find it while the clock is ticking is not what I call fun by any stretch. Also, once I entered a number (not a note) into a block, it didn't automatically delete that number from notes within the 3x3 grid, column, or row. I had to do that manually. Granted, if I made a mistake, it saved me from having to redo all my notes, but it did seem to me to be an overall hassle. I guess the other apps I regularly use have spoiled me.

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.
