I know next to nothing about programming, but I love apps that make me feel like a programmer. Some of my favorite examples on the Mac have been Keyboard Maestro, Text Expander, Hazel, and Automator, each of which allows you to create what are essentially mini-programs, without knowing a bit of code.
The most recent exciting entry in this category is Workflow, which has been called Automator for iOS, and which has gotten some great reviews. As soon as I downloaded it, I set out to see if I could build a workflow that solved a problem I’ve had for a long time: creating a link post directly from within Instapaper on my iPhone. I made a video to demonstrate how I built it.
Update: I've since played around a lot more with Workflow and created this much more robust version of the link post action. This is new version creates a Markdown formatted link post from Instapaper (may work with other apps with the system share sheet) and sends it to Drafts.
First copy some text for the block quote, then run the workflow from the share sheet. You will have the option to input the "link text," which is the text before and inside the brackets. You will then have the option to input "post link text" which is anything that would come after the inline link. Then the workflow will create a Markdown formatted link post in Drafts.
