For true crossplatform p2p the closest I have found is FlyingCarpet [1].

But it is not super reliable or friendly.

We've made the one true, and ultimate, cross platform P2P + E2EE data transfer tool out there.

Both UI and CLI with complete feature parity on any device/OS, between the same user's devices and between users.

iOS App 10€/month Hmm - no.

It's free. doh.

Thanks for the tip. Just tried it and it worked great between MacOS and Android.

Make sure to also try PairDrop https://news.ycombinator.com/item?id=47935875

It's a pretty polished PWA you don't even need to install as it uses WebRTC P2P streaming in the local network or via TURN over internet.

So a good solution for ad-hoc file sharing without ad-hoc network.

I use wormhole.app

Very cool, I didn't know about this. I'll watch it with interest.
