I tried the iOS client yesterday but could not log in (to a well-known third-party server) and the app just did not work at all. The error stayed on the login screen no matter what I tried, and it did not offer any debug info or help, and I just couldn't get past it. I've been developing software for 20 years so I know something about buggy software and different stages of completeness so I usually give open source projects more slack but after 30 minutes I just gave up and uninstalled the app. I really hope these kind of projects get more funding and wind behind them to get a bit more mature so there would be serious alternatives for the likes of Whatsapp.
