So I downloaded it. But when I run it, I just get an error screen saying it’s not compatible. Waste of time. ## Most critical reviews (10 lowest-rated) ### 1/5 — Way off *2023-11-24* Optometrist measured 64 and this app shows 61. That’s a big enough difference to mess with the prescription glasses. I highly recommend against this app and recommend just going to get a proper measurement. ### 1/5 — One small problem *2021-10-25* It asked me to take my glasses off, which is fine but it doesn't hold the reading, so with my glasses on it won't read the IPD and with my glasses with my glasses off I can't read the results. ### 1/5 — Didn’t even recognize my eyes *2021-03-17* Restarted app twice and couldn’t even get a reading. ### 1/5 — Not on iPad *2021-01-06* Suggest you amend compatibility on App Store, won’t work without true depth camera, which I didn’t know was a thing. ### 1/5 — Not compatible with iPad! *2020-11-29* Contrary to app description, It does not work on iPad and clicking on app support button brings you to error 404 page not found. Scam app. ### 1/5 — Doesn’t work *2020-11-06* Feel mislead about this app, I look under the phone requirements and it says that it is supported but it clearly isn’t once you open the app. Only thing I can think of is that the developer is leaving the requirements open to a bunch of different model iPhones and ipads to fraudulent boost the download numbers. ### 1/5 — Half the reviews are fake *2020-10-13* It states my device is compatible, except when you install it, it then tells you that you just I’ve an iPhone X or higher. Wasted my time. ### 1/5 — Why say it works on this iPad/iPhone if it doesn’t? *2020-03-27* Stupid. ### 2/5 — Free but Not accurate *2026-03-20* I trusted it until I used caliper to measure, I put caliper in front of my face to measure distance between the dots IPD displays IPD shows almost 10% more than real distance ### 2/5 — Says Near PD measurement but can figure out how *2023-06-25* It says you can measure both fat and near PD, but only Far is coming up and I can figure out anyway to change it ## Most praised reviews (10 highest-rated) ### 5/5 — Works well! *2023-06-19* I am a licensed optician and try this app out on a few people can report that is pretty darn accurate. I. ### 5/5 — Accurate and immediate *2021-09-30* No gimmicks ### 5/5 — Just the IPD *2021-07-16* The purest app I’ve ever used. Measures your pupils and does nothing else. ### 5/5 — Works great *2021-04-24* Had my measurement in less than 30 seconds. Tried other apps and they didn’t work. Recommend ### 5/5 — Great apo *2021-03-12* Great app! Easy to use. ### 5/5 — 0.1mm off from the optometrist *2020-11-29* Surprisingly accurate for near-sighted measure. ### 5/5 — Simple. *2020-11-14* Short and sweet. Very useful. ### 5/5 — Super super *2020-06-18* Very good. Helped a lot ### 5/5 — Remarkable new use for iPhone X *2019-11-06* Great, useful! Worked on my face with recognition tech. ### 4/5 — Not as accurate as others *2021-09-27* 1cm out compared actual result. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
