~120mb more.
The app overall itself needs 140mb+ in addition. A
Less if you disablelogs (turn off Configure → Settings → Enable on-device logging) entirely.
In the upcoming version, v055o (due in a few weeks, but I’ve been saying that for months… as a forum member here notes) we’ve tried to optimize for RAM usage wrt on-device blocklists (instead of reading the entire blocklists in, we only selectively read what’s needed), some more. Let’s see.
We were nerd sniped by Daniel Micay in to implementing a client-side multi-hop. It works nicely, dare I say, in our testing. And so, wrt hopping specifically, in the upcoming version, v055o, you’d be able to hop any WireGuard over any other WireGuard (for instance, hop Proton over Amnezia, like I do).
