Workflow

Apple isn't a company that is know for their customization of features. It's something Android fans blame Apple a lot for. But now iPhone and iPad users can laugh back, sit back and enjoy massive amount of customization and automation with Workflow and spend less taps to get more work done :)

• Drag-and-drop interface
• Mix & match hundreds of actions
• Encode your media
• Access your favorite workflows right from Apple Watch
• Complete tasks without even opening the app
• Share/export/import content among apps

Most of the limitations you are going to have will come from API limitations and apps themselves.
