I’ve been a big fan of the iOS app Drafts for quite a while. Here’s the premise: open the app, get a blank screen to start typing, then after your thought is out — decide where to send it. One of my biggest uses is to type something and then append it to a file in Dropbox to keep a running list (movies to watch, gift ideas for friends and family, etc.). This video series by David Sparks is a great way to learn the ropes: highly recommended.
