Ok, so it's not a stats calculator, but brilliant at the basic scientific stuff - very near layout. Well done.

This is so typical of developers! There appears to be a move to test a person's patience beyond endurance and is often the reason I delete software and never buy... STOP LIMITING FEATURES, or, at least, stop limiting the use of the software to the point where one can not truly test/trial the app/software. Why not limit the total recording time to say, 3 minutes (that means either 1 dictation of 3 minutes or, say, 3 dictations of 1 minute each, etc.). That way, I can at least give a good chunk of dictation to my voice recognition software and see that it will accept it all. At the price of the full blown app I would want to know this is going to work... or is the developer trying to hide something!?

The app is very good, and as a hard of hearing sound guy the app makes perfect sense. However, it did fail positive on me i.e. said my ears were fine when in fact they're not - mild to moderate loss with severe tinnitus. I'm so used to having to decode what people say in the midst of noise that this was a doddle. Maybe there is a way to apply this method to a frequency based test.
