I have an Android 5.1 phone (Moto G gen1). I tried the CAT app but it 
just crashed at the point of installing the profile. I am happy to take 
this issue up offline with you if you like. It's possible there's a bug 
in the XML profile I tweaked - but I'd still hope the app wouldn't crash!

Also, its terms require prior written permission for non-educational use.

Are there any alternative apps which can use this API?
