Open Mapple

Apple’s open-source XNU kernel and an iOS user space on Android phones, built like an Android custom ROM: a repo manifest, a tree per device, one build command, a zip for your recovery.

It is a research project. Release 1 for the realme 8i is not out yet: iOS 16.7.16 with Wi-Fi, Bluetooth, the speaker, the torch, a passcode, rotation and the GPU drawing the UI. The camera is still being finished and cellular comes later; see the release notes.

Mapple Manager

Our own app for the phone. It shows on the home screen as Mapple, and changes the phone's boot settings, installs apps, and adds tweaks if you want them.
