For months I've been using the free version on a little 2.3 Android phone with lots of fun and wanted more.
I've bought 4.4.2 android tablet, special for this app and torque app and for my surprise on Gappstore says 'your device isn't compatible with this version.'
Copied the .APB files and downloaded .apk installer from Gsearch and it... Worked!!! The free version.
Paid for pro and not surprised, Worked again!
Why G app store doesn't allow me to test the free ver to see if it is really incompatible with my 'device'?
Final thots, work ONLY with the best for the best results.
Happy motoring and control your costs!
