I do use the app but I don’t have the correct paper for the diffuser and I’m not sure how accurate it is… I’d like an apogee but kinda expensive.
Ordinary 20# printer paper is fine to use.
I think what I have is 22 or 24lb paper. I’ll probably order a meter today. Might as well! Definitely appreciate all the comments!

Wow that’s crazy. Thanks for this!
