Umbrel has a relay and runs on Tor. Though might be difficult to use on iPhone directly over Tor.

You tryna wait 10 seconds every time you click a button?

#[2]

yes

There was a relay on this onion url before but I haven't tried it myself so not sure if it's up anymore

https://github.com/Giszmo/nostr.info/blob/master/assets/js/main.js#L226

Not sure if they are still up and running 'ws://jgqaglhautb4k6e6i2g34jakxiemqp6z4wynlirltuukgkft2xuglmqd.onion' and 'ws://wagvwfrdrikrqzp7h3b5lwl6btyuttu7mqpeji35ljzq36ovzgjhsfqd.onion'

I believe #[2] runs one

The Start9 Labs Embassy ones probably have Tor addresses, every service on the Embassy is available over Tor.
