Pros and cons of Sudoku Grab app for iPhone and iPad

Sudoku Grab app good for

I am a big sudoku fan and I have tried so many apps even in my early Palm days, and this is by far the best!!! The OCR is flawless and works like magic. My only minor complain is the location of all button. Sometimes you hit it by accident when reaching the top and bottom rows. Besides that, it is awesome. Keep the good work!!!
Im addicted to sudoku. love this app too. wish that the position of the menu button was at the top of the screen though. When Im trying to select the numbers or the pen, I keep getting flipped to the menu - annoying.
The perfect Sudoku app for couples who both solve the puzzles. For several years Ive entered the Sudoku puzzles on my MacBookPro so my wife and I could both share a puzzle. This is a much better alternative. Please add an easy way to clear pencil marks.
Great app. Wish the ipod touch had a camera but the preloaded puzzles are a challenge. Had a problem after upgrading to V1.7. Emailed (from contact info in app) and received response in less than 12 hours with solution and info that the fix has been submitted to Apple. Great App, does what it says and great customer service. Thanks
If you enjoy Sudoku then youll love this app! Please add support for Extreme Sudoku puzzles.
This app works extremely well at capturing puzzles (even in less than optimal lighting), and it had the best interface Ive usef for solving puzzles on screen. I wish they would make one for cryptoquotes.

Some bad moments

Ive tried several times taking pictures with the camera in a 4G iPod Touch and nearly every time it fails to recognize most or all of the numbers and often puts them into wrong positions or even puts numbers where there are none. Its a novel idea, but the execution has serious problems. Perhaps the developer needs to tweak things for the camera in the 4G iPod Touch. The camera on the iPhone is 5MP (about 2500x2000) and the camera on the iPod Touch 4g is about 0.7MP. Sometimes the program did work with an imported screen shot taken on an iPad and sometimes it did work with the iPod Touch 4G camera. The weirdest thing of all is that with some images I got different results every time I ran the program on the SAME image. After more testing it appears that the problems happen more when landscape photos of other puzzles are used (which I suppose makes sense as there are a lot fewer pixels in that direction). After more testing it does work with the iPod Touch 4G camera some of the time, if you take portrait photos but much less so with landscape ones. But I took several photos of the same puzzle and got different results from each, so the methods the program uses seem to be very picky about the image. Until the developer fixes the problem or Apple puts a higher res camera in the iPod Touch 4G, I would stay away from this app if you use a 4G iPod Touch, or at the least give the Lite version of this program a try before plunking down your $1.99. I do like the Sudoku aspects of the program - its great at solving puzzles, and its very handy for finding slight variations of puzzle solutions by just changing one or two of the cell values. It has the ability to show all the "pencil -Bob
Can’t even open the app now. Crashes on launch. What did you guys do to mess this up? Was working fine before the May 2014 update
For years this was my favorite Sudoku app. The recent update is most unpleasant. Aspects of the app appear to be broken, the graphics are degraded, and its just not easy to play. I urge the developers to revert back to the previous version, which I could happily rate at five stars.
Would have given a 5 before the update. I cant even use the app anymore. Before the update I would get the paper every morning, take a picture of the puzzle and worked them. Over 1700 puzzles, 4.5 years gone. Not that I care about losing the puzzles but am going to have to change my morning ritual. Please fix this so I can use it again. I have deleted off my phone since it kept locking up!!!
After the May update, it crashes every time I launch it. Tried deleting/reinstalling to no avail. Please bring back the previous version--it worked perfectly for years!
How was Vsn 2.0 even approved?? Crashes immediately upon launch.
