don’t know if this is an appropriate community
I don’t particularly like this application, but my whole family uses and they simply won’t use any foss alternative I’ve proposed so far.
I’m even thinking about joining them.
I only need audio, no video calls, no file transfers.
ETA: what free droid apps can do simply that, not needing for me to provide a phone number or my current location / country?


I mean mainstream messaging apps actually used by everyday users. Whatsapp, telegram, etc. While you can use SimpleX without creating an account. It still relies on SimpleX servers to relay to your message.
Briar can work without relays or central servers only using Tor for internet connections if enabled.
Wrong again, it’s decentralized. You can run your own relay.
