Ive had this over four years now. I would not trade it for any other English-Thai app.
Ive challenged this dictionary/translator many times and it has come shining through. There are words I never thought it would have but Talking Thai had an answer 99% of the time, even when I threw phrases at it.
Worth every satang.
