Honestly I cant find the exact one, but Reza Dorrani probably has this in his vids or you can go with something like this:
Tldr - in PowerApps you design the form and buttons, which set a value on a sharepoint list, after which you can set up the view as shown on the vid ive shared. I wish i could help more, but my PowerApps/Automate knowledge is limited.
I dont get it, why use such tooling for metadata?
Lets say you went with iOS notes and picture pulling, then you would just create a table in notes, paste the pic in the firm column and rest of data, such as washing instructions, color, etc. in the others. Heck, now you could just use excel or whatever table app is on iOS, instead of clunky notes, for eg pivoting and do whatever you want to do with it.
