Notes app is fantastic. Once I realised you could jam photos onto notes, set up checklists, make tables, store files on the note etc I’ve been using it constantly. I create job / task specific notes, attach all docs, photos and text notes to it as I go then upload the whole note into cloud storage folders which dumps everything into the folder in one click. You can just scroll through everything on that note without jumping between apps e.g. opening a pdf in files then jumping to photos then jumping back to notes. You just stay on the one note scrolling up and down. Love it
