Amethyst — Open Source Messaging App

Amethyst brings the best social network to your Android phone. Just insert your Nostr private key and start posting.

Nostr is an open protocol that is able to create a censorship-resistant global "social" network, transferring notes and other stuff using relays. It doesn't rely on any trusted central server, hence it is resilient; it is based on cryptographic keys and signatures, so it is tamperproof; it does not rely on P2P techniques, therefore it works.
