Never got past the ‘measuring the screen’ scan. Had to get another person to hold the magnetic strip card in the middle of the 6 blue dots so that I could stand away from it to try to scan all of the dots. I work in IT and have a large screen. Is there a […]

Device not supported. They replied to my first review basically repeating that, and suggested that I try another device, as if I’m going to get a second phone cause the app sucks. Why isn’t my device supported? That’s what I asked the first time. It has cameras on both sides. What specific parameter is it […]

4 different results, 70.0, 70.5, 71.0, and 71.5. I changed cards with magnetic strip as the first card used was darker and second card was lighter. My mobile device security app warned me this was a low reputation app (their words not mine) as it may take pictures at any time and may run in […]

PD measurement works really easy and accurate but then there is the lens prescription scanner! I thought I’d see how accurate it was well… (in a really condescending irritating voice) your phone is too close, your left lens is closer than the right, your phone is too far away, phone is too close, your glasses […]

says the targets don’t show clearly yet I can see them fine and it worked last week. why do we need to listen to the instructions every time. please let us skip. stop turning the volume up. can we have the option of text instructions instead of spoken ones. Speed the process up.

Does Not Work. As dozens of other reviews state, it cannot pick up the six dots on the screen. My camera is study and the lens is clean. The room is well lit and there is no backlighting. It is not blurry or shaky at all. This is a Samsung Galaxy S25 Ultra. The camera […]

It turns on the volume to high level even after I turn down to full silent in every steps using the volume button. It just overrides, regardless what I do. Its access permission is hidden, so I can not control it going to my system settings! Pupils has to be parallel to get exact measurement. […]

I used this to measure my IPD and it worked really easily. Some people in the reviews have said they are worried about the app capturing a image of their bank card. While it is true you need to show a magnetic swipe card in order for the app to properly scale distances, it does […]

Spent 40 minutes trying to get it to scan my lenses through the camera for it to keep repeating that the dots are not visible when they are, camera is too close to the screen when it’s not or to move my glasses back when they’re half way. When it does finally scan it says […]

Tried to use the IPD scan and I kept getting the error “your eyes could not be detected”. I tried moving outside, inside, with bright lights, dim lights, lights in front of me, lights to the side of me. Nothing worked. I guess I don’t have eyes! Edit: Okay so I had to reach out […]

Useless. Spent 30 minutes trying to get it to work. The dots are visible, card is flat on screen and constantly saying “make sure the dots are visible on your mobile device” – 15 mins and nothing. For pupils distance constantly saying “the card is partially hidden”, I only hold the card according to the […]

Very accurate. Matched optician’s measurement and my own measurements using a ruler in a mirror. Also got single vision distance glasses parameters correct. First app measurement was exactly correct while using the best direct lighting against a solid white background and my driver’s license. Second measurement was 0.5 mm under due to non-solid background and […]

Easy to use, and seemed decently accurate. Got three different results depending on lighting and the distance I held the phone from my face. Obviously it’s hard to be 100% accurate with a camera based app. Overall worked for what I needed. In the end one of my three initial results, I got another four […]

Dont use a real credit card even then cover info in electrical tape so no details can be seen. Ran the scan multiple times with a less than .5mm difference on 1 of the 3 tests. Its simple and quite nice. Dont think I’ll keep it installed, nothing against the company, its just that the […]

Seems to work really well. The only thing that made me a little suspicious is that it says to use a striped card as a reference. Striped cards are usually credit cards. It makes me think there might be a potential for identity theft. I used a rewards card from a gas station but in […]

I really wanted to try this and compare how accurate it is to what I got from my optometrist before I purchased a nee pair of glasses. The app can scan everything fine with my camera lenses, but as soon as I put it through my glasses, it tells me my camera is too blurry. […]

this was SO fast and easy! I was hesitant but I tried after reading reviews. as to the concern about cards and security, with things like this, I use a used gift card, or a sample card that came in the mail. back to the app… the process is really fast, with no data entry […]

No matter what I did, even switched from my large monitor to my laptop, it kept telling me I was too fsr or too close to the screen or kept repeating to make sure I could see all the dots on my mobile screen, which I could. If it did finally taken all the readings, […]

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 […]

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 […]
