iOS 18 crash resolved, back to being a great tool

A simple and amazing tool to learn about displays and software settings affecting latency.

Simple and genius

I love this! Was easily able to measure the input lag of my TV by having it mirror my laptop and switching from one browser tab to another. The first time I ran it, it asked for photo access, which was weird. I allowed access to 0 “selected photos”, and it worked fine. (Actually it crashed the first time I clicked the camera icon, but after restarting it, it worked fine)
