Would anyone use a free app that measures centering off a smart phone pic?
 

Yes or no.

Sounds like a registry guy question, concerning technical grading. So for me, no. You can post this question and maybe do a poll on the main board if you want to....my answer stays the same but I might be in the minority. Also, I think this question might have different answers on other, more registry focused, boards.

I would try it, if I was accurate I would keep it. :D

A trimmed app also would be fun. And probably a lot easier to program it to be accurate.

I saw someone mention an app that measures centering, but can't find it through the search engine. Figured I would BTTT this thread since it has a good header. What's the app?

No.
