This is the most expensive app Ive ever purchased on the iPhone, and I was very disappointed that the developers havent ensured its compatible with iOS8. It seems to use a non-standard keyboard system which is incompatible with the new OS. Impossible to enter text in either English or Thai script, which makes the app completely unusable. The only reason I gave it two stars is because it used to be very good when it worked. Hopefully an update will fix the problem and make it usable again.
