UPDATE: Now looking more into PWA (progressive Web app) which may more easily facilitate a starting point for what we need. In part because uncle Jakey just can’t afford an iOS aaand Android developer and all the maintenance and upkeep associated.
In slightly more serious discussions here about building an app for iOS.
Finally it seems since the iPhone X that the tools are available to measure distances accurately, which could give us the basis to skip the measuring tape and get diopter results straight from our phones.
This, just a bit of an update of one of the many things always kicking around in my head, as well as in various stages of exploration.
Big hurdles could be “medical” type claims and whatnot when it comes to app store approval, and things that are tricky to figure out before spending a bunch of money developing a thing that may or may not ever see the light of day.
Feedback, ideas, comments welcome. Currently paying an iOS developer to explore concepts and study feasibility of some techy BITS.
