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

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
