## Circle and Sphere Pro Reviews in United States

### ***** "Great Developer & app"
Works flawlessly, handy tool
Great Developer support
PS- 3rd party Google data mines everything
-- Scaudio, 2024-04-18

### ***** "Change the units?"
This app is great. The only problem I have is it’s in meters. How can I make it feet or another unit? This is pointless if all we get is meters.
