Very very good!!!
It was good since I started using it (in beginning of 2012). But now after the latest update to version 2.3 (mid. 2013), it became very very good and much smarter. It has simple words and verbs conjugation. If you are in doubt because of price (it is not cheap), dont hesitate because it is a good investment!!
