Works on iOS 5, 6, 7, 8, and 9. Mostly works on iOS 10, though with a few features not working. Update 4.0 is coming. Has arm64 support.

mikoto allows you to customize various App Store apps including iOS itself.

Think of it as something similar to Springtomize, but also for App Store apps.

All features are listed and configurable through the mikoto preference pane in the Settings app.
