Added internet connectivity, making it easier to update the positions (only on manual request) and for sending anonymized(*) statistics.
This can be completely disabled under "options".
The number of available puzzles is being shown in the about section, which is #333 initially (or built-in), and - slowly - growing! Once you've updated the positions successfully, they can't be updated within the next 7 days.
(*) No private data will be transmitted, neither your identity, nor the Android Id - this would require permissions which are not being asked by the app. However, you can use the app completely offline as before.
Chessrating 2.5 (internal V 15)
release date: not released on Google Play Store (Amazon only @Dec/17/2015)

The internet permission is only used for 2 things
check for additional positions than the built-in ones

Versions 1.*

Keeping it very simple and without using bitmaps, a True Type Font was used to display the pieces. Chess pieces are included in the basic UTF8 set, so this is an easy task. But it looked somewhat – ugly. The first version 1.0 was published on Feb/29/2012. Targeted for devices from Android V2.1 and better.

Here you can download the last version of the 1.x branch
