It is still in beta so installing it on IOS requires testflight, and on Android messages don't appear automatically. In other words it doesn't look like a communication channel to pull messages is opened. In IOS this was working OK. But it looks interesting, will try it next time. Also it would require more translations (you may say, then just do it, I would reply yes I will, if I use it with friends). If the pull functionality for messages doesn't work well on Android though, Simplex might just be better.
