Latest reviews of GeoCompass 2 app for iPhone and iPad

Excellent app
Well designed. Makes iPhone a highly functional geologic instrument. Even better if elevation could be set to feet and if dip could be read aloud so you dont have to look at the screen when setting position.
Needs instructions
User guide is worthless. Maybe it would help if it had some words. App seems like it would work fine if I could just figure out how to use it. I dont see a pointer and I dont know if the IPad is to be horizontal or vertical. I also dont know if I need an Internet connection.
Instructions please!
I figured out how to take a strike (using the top of my iPhone along the planar surface Im measuring) however the dip I cannot figure out and the pictures in the info section are not helpful! Ive tried every edge of my phone with a known strike and dip surface and have yet to get a correct measurement of the dip with this app. Also, is data coverage required to use the app and store data? Or will it store with our cell service/wifi?? This seems like it would be a very useful app but it needs more support!! Please update!
