# damus
A twitter-like [nostr][nostr] client for iPhone, iPad and MacOS.
A twitter-like [nostr][nostr] client for iPhone, iPad and MacOS.
<img src="./ss.png" width="50%" height="50%" />
[nostr]: https://github.com/fiatjaf/nostr
## How is Damus better than twitter?
There are no toxic algorithms.\
You can send or receive zaps (satoshis) without asking for permission.\
[There is no central database](https://fiatjaf.com/nostr.html). Therefore, Damus is censorship resistant.\
There are no ads.\
You don't have to reveal sensitive personal information to sign up.\
No email is required. \
No phone number is required. \
Damus is free and open source software. \
There is no Big Tech moat. Therefore, seamless interoperability with thousands or millions of other nostr apps is possible, and is how [Damus and nostr win](https://www.youtube.com/watch?v=qTixqS-W1yo).
## If there are no ads, how is Damus funded?
Damus offers a paid subscription 🟣 purple 🟣 https://damus.io/purple/. \
Initial benefits include a unique subscriber number, subscriber badge, and auto-translate powered by DeepL.
Damus has also graciously received donations or grants from hundreds of Damus users, [Opensats](https://opensats.org/), and the [Human Rights Foundation](https://hrf.org/).
## Spec Compliance
