It’s crazy to me how underrated Nymchat as a messenger really is, as it is so much more than geohash or bluetooth mesh. It can function completely as a standalone messenger without any geohash channels. It is NOT a bitchat fork, it is its own built from the ground up messenger. It was the first messenger to solve using NIP-17 for group chats and do it in a way with no meta data leaks or needing to rely or any janky key ceremony or 3rd party coordinators. It was also the first to implement post-quantum resistant private messages and group chats. It’s incredibly feature-rich (auto/video calls both one-on-one or in group chats, voice/video notes, P2P file sharing, photo/video sharing, polls, location sharing, multi-account support, and more), customizable (add-on packs to change styling of messages and nicknames, multiple themes, message bubbles or IRC-style layouts, Tweetdeck style columns view, wallpapers, etc) and with extensive anti-spam and self-moderation controls. It works across multiple devices and securely syncs data/settings. It’s available across all platform; desktop, iOS, and android. And to top it off, it can be locally hosted, without any compiling steps needed.
