Great idea
I like the idea of having the possibility to chat without an internet connection. It would be helpful if you find yourself stuck on the other side of a noisy river with no signal and have lost your glasses, making it difficult to see what your friend is trying to show you while waving their hands. However, there are a few issues. Firstly, there's no way to manage the rooms. Once they are automatically created, you cannot delete them (I finally found the delete button in the detail of the room). Secondly, the automatic creation of rooms is a problem itself. It creates a new room with a picture whether you want it or not, and you cannot send the desired room code later on.
