### 1/5 — Great idea but needs to be fixed

*2026-04-25*

The general concept is excellent, but the app simply doesnt work well.  Trying to image both eyes within a single video frame isn’t possible.  The video is too far away from the pupil to get high enough resolution.  I would urge the app designers to redesign the app. You need to get two seperate videos of each eye alone (with a closer up video at higher resolution). 

Every single high-quality pupillometer in the world that I’m aware of involves separate, close-up video capture of each eye individually.  

I would love to see this app suceed.  I think the overall concept and design is good. I love the concept of iphone pupillometry.  Please fix it so that it works. 

It would also be great to display graphical curves of the pupil diameter over time.
