Wareable.com reviewed version 1.0 and gave it 3.5 out of 5 stars.[7]

Software Architecture

AsteroidOS is built like an embedded Linux distribution with OpenEmbedded.[8] It works on top of the Linux kernel and the systemd service manager.[9] AsteroidOS also includes various mobile Linux middlewares originally developed for Mer and Nemo Mobile such as lipstick and MCE.[10]

The user interface is completely written with the Qt5 framework.[8][11] Applications are coded in QML with graphic components coming from Qt Quick and QML-Asteroid. An SDK with a cross-compilation toolchain integrated to Qt Creator can be generated from OpenEmbedded for easier development.[12]

Asteroid-launcher is a Wayland compositor and customizable home screen managing applications, watchfaces, notifications and quick settings. Asteroid-launcher runs on top of the libhybris compatibility layer to make use of Bionic GPU drivers.[13]

AsteroidOS offers Bluetooth Low Energy synchronization capabilities with the asteroid-btsyncd daemon running on top of BlueZ5.[14] A reference client named AsteroidOS Sync is available for Android users.[14][15]
