App Store Reviews

If you like the app and think it's great (or if you think it's rubbish) I'd love it if you could write a review on iTunes.

If you really hate the app then please email me on sudokugrab@googlemail.com and let me know what you think should be changed/improved.

Japan

That new video that was posted on YouTube (available here) came from a Japanese website. Yesterday Japan went crazy. 46 copies sold!!!

I think I will start to internationalize the app - starting with Japanese!

Unfortunately the rest of world seems to have fallen asleep :( So no yacht yet.

Still waiting for version 1.01 to go live... Work has started on 1.1 I'll post some screenshots for review in the next couple of days.

Reviews

So far the app has received two 5* reviews! - one in the UK and one in the US. Thanks so much for the feedback. It's great to know that people are finding the software useful.

There's a great site here that lets you see all the reviews for Sudoku Grab in every app store.

If you go here you can give it the url of any app and see the reviews. Very useful if your own app store doesn't have any reviews yet.

Sudoku Grab in action.

These videos are all of version 1.0 but they still show the cool camera grab facility.



I thought the theme tune from Think Of A Number was appropriate...

Just having a quick look on YouTube and there's another video from someone else!



Does anyone read Japanese?

Version 1.01 submitted to the app store

This fixes a couple of UI issues and addresses a crash bug that shows up occasionally. There is also a tweak to the puzzle location algorithm to improve performance.

Since I was making changes anyway I've rolled in the change to highlight obviously incorrect numbers on the number recognition screen that was scheduled for version 1.1

Known Issues

If you are having problems with the latest version then please try the following steps:

• Power off and restart your phone - this should resolve issues with taking photographs of puzzles


• Uninstall Sudoku Grab completely and download it again - this should resolve any issues with the upgrade process not working as it should

If you have any problems then please get in touch and let me know.

Road Map

I've split Version 1.2 into a 1.1 and a 1.2 release as it was starting to look quite big. Thanks for all the feedback.

• Version 1.01 (Submitted to App Store)
  
  • Highlight obviously wrong numbers on the number recognition screen.
    If the recognised numbers don't correspond to a valid sudoku puzzle we should be able highlight the conficting numbers.
    
  • Change info page so that help is displayed as text and not in a web view (it's just too slow and memory hungry).
    
  • General Bugfixing.


• Version 1.1 (development started)
  
  • Label captured puzzles with difficulty, date and source
    (Thanks for the feedback Phil)
  • Add a confirmation dialog to the solve button (thanks Lee).

• Version 1.2
  
  • Email a friend - send a grabbed puzzle to a friend.
    Launch an email with the puzzle contained in url that will launch Sudoku Grab on a friends phone when they click on it.
    
  • General Bugfixing.
    


• Future
  
  • Upload character training data and download new OCR
    It would be great if incorrect numbers could be uploaded to a central server to train a new OCR system that could then be downloaded automatically.
    
  • Update OCR system to correct errors
    If you identify incorrect numbers retrain the OCR system so that it improves over time.
