I have an iPad Pro 9.7 inch. I am a photographer that doesn't like a lot of paperwork. I am trying to find a solution to keeping up with my PDFs. I have client files on my iMac or should I say iCloud Drive. I am trying to locate the best way to annotate and highlight relevant information for wedding details. I currently use Onenote. I have been known to change my note apps from day to day. I used to use Evernote, but I left them earlier this year and hadn't thought of going back. I have used the Apple notes app also. I also have Notability and GoodNotes. I like Onenote because of how easy it is to organize my notes. I can also write notes next to whatever I type. I can even cross things out with the Apple Pencil. But today, I found out that I cannot highlight PDFs. Is there something that I'm missing? Which notes app do you use and why?
