Federico Viticci has created a masterpiece:
Since the original release of Workflow in 2014, we’ve created hundreds of automations to help readers use their iOS devices more efficiently. The goal of this archive is to offer a complete catalogue of our old workflows as well as new custom shortcuts for Apple’s Shortcuts app.
Each shortcut in this archive has been created, updated, and tested by Federico and the MacStories team. Shortcuts are organized in categories, and you can jump directly to a specific category by using one of the section links below.
There are some amazing Shortcuts here, and my favorite part about all of this is that they can become a jumping-off point for your own Shortcuts. What an amazing resource.
