Apostrophy OS is a new smartphone operating system aiming to be a third choice between Android and iOS.
The OS is based on Android but heavily modified for user privacy, offering complete control over personal data.
Apostrophy OS features a unique home screen called the "Domus," a customizable home screen called the "Piazza," and a suite of apps and services focused on privacy.
so... basically Android?
Specifically, Android 13. Not even the latest version.
