Evil Scheme

Evil Scheme takes advantage of iOS URL schemes to allow users to change default apps in which links open.


Default apps can be set in the Evil Scheme preference pane within the Settings app. To add a default app, select the highlighted Add new row. Choose a preset, or dismiss the view to build your own. To apply your changes, return to the primary Evil Scheme menu and press the Save button in the top right corner; no need to respring! Try opening a link that would typically open a stock app, and viola, your selected app should open!

Creating Custom Presets

Take a look at the user manual for an in depth look at creating your own presets.


You can install EvilScheme for free by adding the Dynastic Repo to your favorite package manager. It can also be compiled from source if that’s your thing using Theos or DragonBuild.

What's New

  • Tweetbot preset
  • Improved logging functionality

Known Issues

  • Siri will not open the selected default app. I’ve looked into this, but I wasn’t able to get it working reliably. If you’ve done any work reversing SearchUITableViewController and how it interacts with ResponseKit get in touch :)
  • Using the Spark preset, occasionaly the app will open, but new email will not be composed. I think this is an issue with the Spark app itself, and I’ve contacted the developers.
