At least checked it out while was free

Saw on apps gone free and decided to check it out since wanted to measure a large room without getting out the tape measure. Only instructions are to calibrate the device. Didnt see option to actually measure unless it the calibration screen doubles as the tool.

Doubt was working right since was giving me negative measurements along with random positive ones. I was holding the left earpiece against the mic as pictured the whole time. Only potential seen is as an entertainment app to annoy others with the horrid sound it emits during use....
