Not Bad, not bad at all!
With the touch of the app it seamlessly transitions you straight into a very nicely laid out open field view that is ready to go and gives you all kinds of readings. Take that with a grain of salt as I don’t have a real range finder to test accuracy. An addition that I would suggest is an option when you go to your phone settings to set the app settings that allow for access to the Camera, to be an option to allow for access only when in use.. for a moderately private person that would increase the user experience. I say 5 Stars
