Buggy. had to restart it 3 times as it just sat there after scanning the QR code. on my p 8 plus. a restart step button would have made this 4 stars, and better placement for the dots would have made it 5. the visualization videos ok but its too quick and not obvious it's there if missed. my frames have bent hinges so they kept folding up. I imagine they needed to be open so I managed with great difficulty unsure if even necessary due to poor feedback. needs polish. I will check back and update

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.

10/10 - I couldn't find a mm ruler on hand, and I was actually having a hard time measuring to begin with. I almost gave up til I saw this app. I scanned three separate times, and two were the same, and the other was extremely close. Not sure if I would've figured it out without this. It is super easy and doesn't even take 5 minutes. For those worried about using your credit card, I just used my license and it worked fine. Will be back to this app for sure!
