Pop for iOS
Pop is simply a convenient place for writing things down — that piece of paper you grab to write when you have an idea. It doesn't help you do anything smarter or more organised.
'Copy All' and 'Read' are the only features, to make it easy to use your words or read uninterrupted. Anything else seems to add a little more noise, a little less focus. Sometimes you don't need more features.
The little extra effort of having to Copy All and Paste your way out encourages quality and focus. If the words aren't worth a copy and paste, clear the page.
