Local send works well for me between android and iDevices in most cases. I will say it struggles with VPN’ed connections, which is by design of the network and some VPN will block local connections.

I know sharedrop.io uses a similar web based model as pairdrop and runs into the same VPN issue, but I’m curious if the room function might overcome that in pairdrop.

I’ve been working with this issue for along time. Trying to find something platform agnostic and works with vpns.

App wise, I suggest Localsend for files

Information wise, I suggest Saladroom although there are several alternatives as well like ToffeeShare and ShareDrop

I mostly use Signal though, as it’s the simplest at hand app which fairly reliably makes it accessible to my various devices… With the downside of storing it.
