### 2/5 — Couldn’t even use it for my purpose

*2025-02-28*

This is not the worst app I’ve ever used, and even the ad supported free demo is usable, but my understanding was from the description. I could measure relative distances with photos with one known dimension, then determine other measurements that were not given in that photo with an iintetpolated app generated ruler? After asking for permission to access my photo library and launching the app and watching the tracking instruction videos, there was no indication on how I can even access that photo so I gave up.
