Our verdict on Nymchat

Nymchat is a free, open-source messaging app built on Nostr for people who want pseudonymous communication across mobile and web. It creates identities as device keypairs, so users do not need a phone number, email address, or Nymchat account. The feature set includes private and group end-to-end encrypted chats, public channels, file transfer, reactions, translation, peer-to-peer audio and video calls, and Lightning tipping. Android and iOS apps can relay messages over Bluetooth mesh when internet or cellular connectivity is unavailable; a Progressive Web App runs in browsers.

Its appeal is the combination of network options and messaging modes. Nostr relay-based messaging is paired with Bluetooth LE mesh for offline mobile use, while channels can be geohash-based or named. Integrations include Nostr, Bitchat, Bitcoin Lightning, and WebRTC. This breadth suits users looking for both public and private conversations, with calls and payments in the same app. The mesh capability is specifically described for mobile, so it should not be treated as an offline feature of the browser app.

Nymchat itself has no subscription, and the published pricing model is free. Optional Nymbot credits and cosmetic flair are purchased over Bitcoin Lightning, so users who want those extras should account for that distinction. Deployment options include cloud, self-hosted, and mobile; support channels are email and docs. iOS distribution is through TestFlight rather than the public App Store, which may not suit people who want a standard App Store installation. Nymchat is a fit for mobile users interested in Nostr and mesh messaging together; those who do not need decentralized or offline messaging may prefer a simpler messaging app.
