damus

A twitter-like nostr client for iPhone, iPad and MacOS.

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. 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.

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, and the Human Rights Foundation.

Getting Started on Damus

Damus iOS

1. Get the Damus app on the iOS App Store: https://apps.apple.com/ca/app/damus/id1628663131

⚙️ Settings (gear icon, top right)

• Relays: You can add more relays to send your notes to by tapping the "+".
  • Find more relays to add: https://nostr.info/relays/
• Public Key (pubkey): Your public, personal address and how people can find and tag you
• Secret Key: Your private key unique to you. Never share your private key publicly and share with other clients at your own risk!
  • Save your keys somewhere safe
• Log out

🏠 Personal Feed (home icon, bottom navigation)

• Feed from everyone you follow
• Can post notes by tapping the blue + button

Notes (under 🏠 Personal Feed)

• Sending a Note is easy and it goes to both your 🏠 Personal and 🔍 Global Feeds
• To tag a user you must grab their pubkey:
  1. Search their username in the search bar at the top of the 🔍 Global Feed and click their profile
  2. Tap the 🔑 icon which will copy their pubkey to your clipboard
  3. Go back to your 🏠 Personal Feed and tap the blue + button to compose your Note
  4. Add @ directly followed by the pubkey (e.g., @npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s)
• You can also tap the ellipsis menu of a Note (three dots in top right of note) to grab their User ID aka pubkey or Note ID to link directly to a Note.
• Currently you can't delete your Notes in the iOS app
• Share images by pasting the image url which you can grab from nostr.build, imgbb, imgur, etc. (i.e., https://i.ibb.co/2SHZbwm/alpha60.jpg). Currently images only load for people you follow in the 🏠 Personal Feed. Images are not automatically loaded in 🔍 Global Feed
• Engaging with Notes
  • 💬 Replying to a Note: Tap the chat icon underneath the note. This will show up in the users’ notifications and in your 🏠 Personal and 🔍 Global Feeds
  • ♺ Reposts: Tap the repost icon which will show up in your 🏠 Personal and 🔍 Global Feeds
  • ♡ Likes: Tap the heart icon. Users will not get a notification, and cannot see who liked their note (currently, web clients can see your pfp only)

💬 Encrypted DMs (chat app, bottom navigation)

• Tap the chat icon and you'll notice there's nothing to see at first. Go to a user profile and tap the 💬 chat icon next to the follow button to begin a DM

🔍 Global Feed (magnify glass, bottom navigation)

• View the Global Feed from all the relays you've added in ⚙️ Settings. Currently you can only search hashtags and user names and pubkeys

Contributing

See docs/CONTRIBUTING.md

Privacy

Your internet protocol (IP) address is exposed to the relays you connect to, and third party media hosters (e.g. nostr.build, imgur.com, giphy.com, youtube.com etc.) that render on Damus. If you want to improve your privacy, consider utilizing a service that masks your IP address (e.g. a VPN) from trackers online.

The relay also learns which public keys you are requesting, meaning your public key will be tied to your IP address.

It is public information which other profiles (npubs) you are exchanging DMs with. The content of the DMs is encrypted.

Translations

Translators welcome! Join the Transifex project.

All user-facing strings must have a comment in order to provide context to translators. If a SwiftUI component has a comment parameter, use that. Otherwise, wrap your string with NSLocalizedString with the comment field populated.

Awards

Damus lead dev and founder Will awards developers with satoshis! There may be nostr badges awarded for contributors in the future... :)
