Hi I tried your app recently, the main issue that I had was that it had a tendency to drop messages, also the uploading a profile doesn’t currently seem to work (on mobile Firefox at least).
But anyways I love the application concept and it seems like you have made some pretty good progress.
P.s. what is the crypto signature box that you can just draw in?
(Also I think you could probably fit the offline connection into one QR code if you really wanted to (117x117 but still))
