I’m asking for Android specifically, but I’m curious what else is out there.
For example, some apps work without internet but may use it if it’s available. I might want to block that without having to turn off wifi, force stopping it, and wiping the cache/data.
Similarly, maybe I only want to use the app over a VPN and want to prevent accidentally opening it without first turning the VPN on.
From what I’ve seen, it can block the Internet for all the OS, not for single apps. But I’m not using that app, so I may be wrong.
In the picture its blocking the internet for a single app - that app being “blinkist”. You mean you want to block Google Play only?
Oh, I see! I missed that. Is it possible to block the Internet to Google Play Services?
No, I think that is a whole different kind of “system”. Download the app and test it out :)
