Updated app version on Amazon appstore

Dear users,

New version is available on Amazon appstore. We fixed bug which could pop up after selection skill level
"2nd grade end".

All is working correctly now!

Description of the bug

We find out that after selecting "2nd grade end"  in option "skill level" you can experience certain problems in  "comparison" and "find element" tasks ( application can unexpectedly stop or you get task "12 + [ ] =27" without possibility to solve).
If you encounter such problem in version you downloaded before 4th of April, please enter into menu  "options" then select "tasks to do" and then press OK or just exit. After that app will work without any problems.

Let's do the math 3 is coming !

We are preparing new product. It is aimed mainly in a bit more experienced young student. It will contain new types of exercises and new types of calculations and new "clay tablets inspired" user interface. Stay tuned!

Score calculation

Score calculation is introduced in latest version available on Anroid Market. App will count your score from now on.

Every correct answer makes your score grow by one. What is more important it is possible to compare your score against scores of other users across the world! So you can see your position across continents.

Communication of the score over internet is performed only after configuration in settings option. NO PERSONAL information is transmitted. Only your score, your continent and technical id is transmitted to central server. Score is stored on secure Amazon servers.

To  prevent bad habits and save the environment , score is refreshed only one time a day.

This functionality will be implemented in Amazon  versions in few days.

Happy New Year 2012 !
