transferpricing

I am a big time Stalla fan too, having used their L1 and L2 materials. But the app is very very very very buggy Content wise its not bad, but usability is very poor mate. But its quite buggy and could hardly use it properly..
Note: I didnt buy the full version, since I just was not satisfied with the performance of the app. Issues I noted:
1. Sudden/frequent crashes
2. Mobile heating up and battery drained very fast. (Because I like Stalla, I would blame my mobile for it though)..
3. Content were quite good, but user interface wasnt good at all IMHO.
So I wouldnt buy this again (hopefully I wouldnt need to if I clear) unless they offered me free test use for a week to checkout performance..
