I have check their app as what i have said yesterday and heres what I've got. I was stucked on the registration i dont know if the app had some bug or something and what annoys me is the color of their registration form which is red can't really tell if there is something wrong with my username or password cuz i have already change and double checked it many times, it only gives me loading when i try to register then nothing happens.
Just to be fair here, they was clear that this is just centralized temporary version and it's not perfect and that the server will be down many times. The reason why they released it is to get feedback and fix errors in order to make decentralized version. So if you was expecting a ready app that could immediately be use to chat with friend, then you misunderstand. I also think is waste of money to make this centralized version well designed when it is just a temporary one.
