Island

What is “Island” “Island” is a sandbox environment to clone selected apps and isolate them from accessing your personal data outside the sandbox (including call logs, contacts, photos and etc) even if related permissions are granted. Device-bound data (SMS, IMEI and etc) is still accessible.

Isolated app can be frozen on demand, with launcher icon vanish and its background behaviors completely blocked.

How does it work Island takes advantage of the “managed profile” feature on Android 5.0+, which is also the base of “Android for Work”, to create an isolated sandbox for apps with their data.

App needs to be cloned in Island first. Afterwards, the clone can run parallel aside from the original one. (even with different accounts signed-in) It can be frozen on demand by Island. (NO ROOT REQUIRED)

If Greenify is also installed, apps can be frozen automatically by “Auto-freeze with Greenify” action (in the overflow menu), just like normal app hibernation in Greenify.
