On iOS Cordova works great, not so great on Android (I'm talking about game programming obviously) especially on Android 4.4.
A dictionary — being text-based, with very few animations, and no background soundtracks — avoided most of mobile-platform-specific issues.
It doesn't work so great on Android, but I wouldn't go so far as saying that every Cordova app is garbage :). For some apps it works reasonably well, for others simply doesn't work.
