Lynk is a messaging app that uses Bluetooth to identify all other users around you and lets you direct message them or create group chats of any size.
It's not anonymous or mass group like Firechat, so you can tune in to trust-worthy sources of information and keep track of your friends or people you meet at the protest.
Does not use GPS to identify your location, and all traffic is encrypted over the wire. Does require a network connection, though.
Disclaimer: I'm co-founder of Lynk and was at the protests in HK last night. Happy to answer any questions for anybody interested in the tool.
