Almost what I want it to be – Pro Compass Review

I like everything about the app, but would like one addition. I'd like to see an setting allowing adjustment +\- of so many degrees to make it more accurate. I know the app is limited to the info it gets from the phone, but to be able to set it to compensate for the phones deficiency would be awesome. As it stands now, mine is about 10 to 20 degrees off from my Trimble/meridian setup I use at work.
