I've spent the last few days creating workflow actions for posting images from Adobe Lightroom to Instagram, opening images for editing in VSCOcam, to creating new blog post -- like this one -- from snippets in Pocket. I'm addicted.
Workflow is an automation tool for iOS. The concept is similar to Automator for OS X. You can run a series of actions to perform a task, such as retrieving the latest screenshot and save it to Dropbox, or you can send anything from share sheet as input before running these actions, such as resizing selected photo from Photos app.Sutanto
