Waste of time. It doesn't work. People who rated it 5 stars obviously haven't used it. It's clunky and awful. Why would i pay money when they can't get the basics right?
Bad math The app refused to give any kind of useful readings. I got out a couple of tape measures and manually adjusted the height until things were correct. I had to set the height at 2'9" even though the phone was 5'6" height. After that the values were correct but something is very wrong with the base formula they use.
Hated it 0 accuracy. Things in front of me are max 1m away but the app says about 500m... Not working correctly on android!
Upside down Not user friendly. Can't get reasons without upgrade. No point in the free version.
I paid for the upgrade O paid for the upgrade and now you want me to pay again? CROOKs! I even have my receipt from Google play and # to back it up
Really I am two 4 feet away from printer and I ruled out my height and tells me I am 8m away
