I just have uploaded a new version to the market. It has many improvements on stability of the app. And I've also included the new feature I told you some time ago. It's support for QR codes.
Now with the camera of your mobile you can check which numbers of a bingo card has been called. You can download printable pdf files with bingo cards and theirs QR codes from this site and play with it.
I will probably upload a video tutorial of the app soon. Regards and I hope you like the news in the app.
Updated: 1.4.1--> bug fixed. Thanks for reporting!
So important report like two users has done today, via report button on the force close dialog, it let me find the bug and fix it. Thanks so much!
