Anybuffer
I use clipboard manager apps in a couple of different ways on my iPhone and iPad. The first way is as long-term storage. I stash documents, snippets of text, and URLs that I need to send to people over and over, which is easier than digging around in the Files app or Dropbox.
Second, I use clipboard managers as a short-term holding pen for all sorts of information. Sometimes I’m combining an image, some text, and a URL from different apps. Other times, I find something I want to send to someone later, and I don’t want to lose track of it. Lately, I’ve been using Anybuffer for both situations. The app has been great, but with the latest version that supports widgets and the new iPad sidebar design, Anybuffer has taken a significant leap forward.
Anybuffer can’t autosave your clipboard if it is in the background, this is a limitation of iOS. This means that on iPhone you have to switch to Anybuffer to trigger auto add, on iPad the easiest way is to keep Anybuffer in Slide Over.
