Doesn't work. On laptop it is unable to recognize the dots on the screen and keeps prompting. *Edit - this was attempted in various lighting conditions with no backlighting and repeatedly cleaned lenses. If the app gave some indication of what it could recognize and what it couldn't, the usability would greatly improve. At one point the app told me I was too close, immediately followed by I was too far away without me having moved

It seems like your device had some focus problems which are affected by lighting conditions and how clean your camera lenses and glasses are. Please make sure you clean the camera lenses and your eyeglasses before starting another session. We would recommend performing the scan in a well lit room with no bright backlights or screen reflections.

This app does exactly as advertised; perfectly. Simple to the point interface, rather, it's the better clean that even most of the top apps don't have. By that I mean no useless "features", no pandering of services that I didnt ask for nor need, and more. Put it this way, I don't normally write reviews at all, but since this app saved me time and was properly built, it's only proper for me to give thanks. I'd say more positive things, but Google's 500 character limit is telling me to shut up.

This app is really easy to use and pretty darn close also. I mean if you're using it to get the IPD on your VR headset at the right setting this app will do the trick without needing a stupid ruler. I did it three times to see if it was going to be different results each time and was surprised that the readings were consistent. Not only that, but I had already had my IPD on my headset at the right setting. So this app pretty much just gave me confirmation that I was using the right setting.
