Mullvad on my desktop. They don't have a mobile app available, unfortunately.

I use a de-Googled phone with /e/OS installed. Works like a dream!

You can also go to https://plexus.techlore.tech/ to check app compatibilities. I discovered new apps via https://switchdigest.eu/.

You might find something here? Not sure...

Cool! I should also visualise my stack like this!

Maybe you can also anonymously declare your switches to switchdigest.eu. Would be cool to show others what we are switching to!
