Fully FOSS and you can use without Google too! Goto settings and select Database encryption with Passphrase!
Discussion
Same can be said of Signal. FOSS, usable without google. But, I guess if you want a little extra encryption (Signal is already encrypted), I guess Molly would be just fine.
Is it interoperable with signal? Can't get family to swap again, signal was hard enoigh.
Also future of messaging through nostr???
