well vetted

I found any website that allows you to use web cam or device will lure you in with their measuring tool, only to hit a paywall or find you need to order. For $2.99, and especially if there are a few family members it's worth it. If you don't get fitted for frames at your exam you likely don't have your PD. I want the value of online frames, so need the PD.

I took my measurement twice for both assurance and experienced drawback with tool: when aligning the target over your drag it with your finger which makes it VERY difficult to see if your are centered because your finger controlling the target is over the eye.

Developer feedback: make the targets have a control pad (4 directional arrows or what ever can be done) so that you can move the target without covering the eye!

Not bad


I had my boyfriend measure my pd a few days ago and he said it was 63 then I asked him a day after to check it again just in case and he still said 63 but then he said 64.

I didn’t doubt him but I needed to make sure the measurement was right so I got this app and it said 63.5 which honestly sounds about right.

I took 2 different photos and I got the same measurement so I can’t believe the app is pretty accurate c:

Easy to use and accurate


Works like a charm. Super easy to use -- all you need is your iPhone or iPad camera and a credit card (for scale). Recently went to my optician for new glasses. He insisted on measuring my PD even though I told him I already knew it. His professional equipment gave me the exact same measurement -- to the 1/2 millimeter -- as this app.
