What worries me about nostore on iOS and a reason I’m yet to use it is although it’s open source there’s no way to guarantee as far as I know that the App Store build hasn’t been modified before publishing (without purchasing an apple developer license and building from scratch). There’s many clients I want to try on mobile (web) but end up just using them on desktop instead with nos2x.
I haven’t fully grasped nsecbunker but intend to dig into it more when I have some free time.
