User reviews

Very useful for vehicle camping

This is the best application that I have used for quickly leveling a vehicle in two dimensions when camping.

Terrible

Its the most useless app ever!!

Pretty useless

I went through a bunch of these to see if any were better than eyeballing it. Quick answer, no. Tried to use it to level a stove. First your case will mess it up. Even without a case, it indicated level when I can see it’s not. No surprise as the others were the same.

Not precise enough for me

Only displays to whole numbers. I need .1 degree display. Works well if you don’t mind being off by up to .5 degrees.

Pictures don’t have gps location

This is a nice app, but sadly I’m still searching for a better one. I use this type of tool to measure slopes every day. It’s great that I can take a picture of what I’m measuring with the slope bar superimposed over the image and save to my photos (with permission of course). But it fails in the the gps location is not encoded with the photo so that I can then do a PLACE search in iPhoto to find this data later.
