Please stand still and look straight at the dot.
It keeps saying perfect now stand still and look straight at the dot. But, it doesn’t progress and doesn’t say anything till I open my eyes wide. Over multiple measurements it varies enough that I don’t trust it.
Doesn’t work
Tried for 60 minutes, unable to get a single reading. Using brand new iPhone 16 pro max
Worthless app
Tried for 30minutes to get it to scan but no dice, keeps alternating between place head in oval and too far even when I matched the red and white ovals.
Does this work with iPhone 17 Pro Max?
Unable to get a ‘lock-on’ from this app when on the ‘place your head in the oval’ screen. Tried various artificial and natural daylight setups and phone mount solutions but no joy. Other apps in the AppStore work just fine and return PD results so don’t think it’s eye colour or iPhone distance/movement configuration issue.

Impossible
Using an iPhone 16 pro max you can’t possibly calibrate it. Doesn’t work at all
Trash
Does not work. Waste of time.
Waste 15 mins just trying to align my eyes
I’m wearing prescription glasses and I can’t see clearly without my glasses. The apps require impossible perfect alignment to measure the pd value, but I am not able to do that without my glasses. Very frustrated. I will just use a mirror and ruler I guess.
Does not complete
I had it in the oval but does not complete the measurement at all
Not helpful
Move your into the oval, you’re too far, you’re too close. My arms were aching after holding steady for so long and it still didn’t give a reading
Have time to use it
The scan takes way too long. I don’t have enough patience to put up with it.
Terrible
As many have said it just keeps asking you to put your head in the oval, no matter how much you try your head will never be in the oval.
What a crack of 5hit
I’m an FBSO. Took 30mins to get this to produce a result and not accurate to known clinical result.
Awful
Never measures. Just says put your head in the oval and when it is in the oval says you’re too far away.
Does not work.
Did anyone test this app?
Trash
Not working at all
Impossible to use
Impossible to get a scan with the 16-May-2026 version. Calibration is impossible, with *very* slight millimeter-level phone movements being called too close or too far.
If you manage to achieve the correct distance, the slightest movement will quickly cancel the scan countdown and send you back into the endless calibration process.
It would probably be easier if they allowed you to set your phone down and adjust your head position, but the app currently requires a specific tilt angle, requiring you to hold your phone in your hands.

Rubbish
Said I was in the perfect spot looked into the dot on screen for minutes waste of time
Unreliable
Differing results each time used, therefore unreliable.
The glasses suppled by glasses direct, who insisted on this app being used, had to be returned for a refund (at least no issue there) as they were unusable.

Useless.
Just a word of warning. If you have a beard forget it . This will not work. It keeps saying uncover your face.
