I’ve tried it. It’s very slow. The app on iOS has two “modes” to choose from when connecting. One is labelled “Fast (Wireguard)” and the other is labelled “Anonymous (Mixnet)”. The “Fast” mode is still two hops so it takes forever to establish a connection. You get to choose the entry and exit nodes though. The “Mixnet” is 5 hops. Slow af. Barely useable at all.
