Useless app

Mapped all of our planes 60 degrees to the East wrong and had some weird bug with the colours. Not worth the $5, pretty much a scam

A must have for geologists

Simple and efficient alternative to bringing a bruntun with you in the field. This one doesn't cost 300$. Just get it.

Crash and burn

Crashed every 5 minutes and lost all the data. Not acceptable. iPhone 5.
