## What it is
Damus is an open-source, Twitter-like client for the Nostr decentralized social network protocol, built in Swift for iPhone, iPad, and macOS. It supports zaps (Bitcoin Lightning payments), encrypted direct messages, and censorship-resistant posting without requiring personal information.

## Use cases
- post and read notes on the nostr decentralized social network from an iPhone or iPad
- send and receive bitcoin zaps over the lightning network
- use a social network without ads or algorithmic feeds
- sign up for social media without an email or phone number
- send encrypted direct messages on nostr
- use a nostr client on macOS

## When to avoid
- you need a mainstream social network with a large centralized user base like Twitter/X
- you need an Android or web nostr client
- you require full compliance with all current Nostr NIPs, as Damus implements only a subset
