With Workflow, your imagination is, in many ways, the only limit. And that can also be a problem at first. Facing the potential of Workflow and the breadth of its actions can be a little daunting; fortunately, the app makes it easy to get started and experiment.
The first thing you’ll want to understand is which kind of task you want to automate on your iOS device, and why. My suggestion, if you’re new to automation: Find common tasks that would truly benefit from requiring fewer seconds each day. They don’t even have to be extremely complex; something simple will do. When automating, it’s better to save a second on a trivial task that you repeat 10 times a day than to save 30 seconds on an impressive workflow you only need once a month.
A good starting point for those of you who are at a loss. I love the app myself. In fact, I used my own workflow to publish this post.
