NYM

Ephemeral geohash and Bluetooth-mesh chat client built on Nostr, bridged with Bitchat

Mobile appfree

Nymchat (NYM) is an open-source, ephemeral chat app built on the Nostr protocol and bridged with Bitchat, offering pseudonymous messaging by geohash location or named channel with no registration required. It supports end-to-end encrypted private and group chats, offline Bluetooth-mesh messaging with no internet needed, and quantum-resistant encryption. It is aimed at users who want temporary, privacy-focused communication rather than a persistent social identity.
