Good news everyone! Apple has just added WebRTC video calling functionality to its roadmap for Safari, which means that all of you on iOS with no choice but to use Safari1 can expect to be able to make Cyph calls just like your friends on Android.
No word on exactly when this will be ready, but my best guess is next year with iOS 11.
