The real purpose of building app with ionic is to develop cross platform mobile app. I am following and developing app in ionic since it was in alpha. I really appreciate how much ionic has grown in past few months. But I can see ionic has very less focus on Android platform. The same app when compiled to IOS, it performs almost perfect but if it is compiled to Android, both UI and performance looks sluggish. I can understand, one of the problem might be because of poor android browsers but another problem might be less commitment of team towards Android platform.
