iOS: Workflow is a fantastic little app for creating various automation schemes on iOS and today it gets a handful of new features that will allow you to overlay images and convert text. One of the most useful new features is the option to overlay images. With this action, you can instantly overlay images you select on top of each other. If you do a lot of repetitive image tasks, this makes them much easier. If you're a Markdown fan, Workflow can now instantly generate Markdown from rich text, which saves you the need for a variety of third-party apps. Beyond those two new actions, you can now unzip files without dealing with another file manager, snag device details instantly and add frames to GIFs.
