RIDGID Level

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

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.

The way this app is designed requires a completely flat surface to “calibrate” the app. However, all this truly does is zero the level. To calibrate is a multi-step procedure which involves taking a reading, then rotating the device 180 degrees and taking another reading, the device should then be able to calculate a true zero. However, the procedure used by this app will only read as level as the surface one zeros the app on. Yet there is no way to know if that surface truly is level.
