4 stars: not sure why everyone is having trouble in the comments. fairly straight forward, accurate, tested on a Galaxy S9 (no purple photo, it saves just fine...). iOS version is easier, but referring to functionality this works just as well
5 stars: Worked great on my Pixel 3. I tested the accuracy by measuring a known 18x18\
5 stars: Very impressive, I tested it on 2 objects and it measures the 2 objects perfect to the centimeter. I didn't think it would be this accurate.
4 stars: Very good concept but at least on mid to lower range smartphones, execution isn't great. Lighting \u0026 similar colored objects make it unable to recognize a horizontal or vertical surface 5 ft away.
4 stars: On a galaxy note 8 it's a little finicky. Need good lighting. Not real bright. Not too dark either. But seems fairly accurate. \
5 stars: Very accurate measuring app, I recogn is one of best, easy to use, the only thing I'm having trouble is taking photo after the measurements done, all I get is a dark blue screen. Have to use screen capture to record the result.
4 stars: Cool but needs improvements. My figer obsures my view when I drag the distance tool. It makes it hard to measure things.
3 stars: I tried taking pictures in the app using p20pro, it just shows me a blank purple photo in my gallery, don't know why. All my initial measurements are useless now. was hoping for a solution to this. the measurement is fine, fairly accurate if you wanna quick measuremen...
