Firechat
Firechat is a secure wireless peer-to-peer chat app:
Firechat is theoretically resistant to the kind of centralized surveillance that the Chinese government (as well as western states, especially the US and the UK) is infamous for. Phones connect directly to one another, establish encrypted connections, and transact without sending messages to servers where they can be sniffed and possibly decoded.

Firechat requires users to create an account and does not encrypt messages in transit or on the device. As police stand quite close to active protests, it would be trivial to intercept messages, spread falsehoods, and track unique bluetooth/wifi identifiers. Even the creators do not recommend using it for secure communication.

I do hope interest in this space creates software that can offer some level of security to its users. Serval Mesh seems to be a step in this direction.
