It is one of my favourite platform to develop mobile apps, it has many tools which help me build better app faster than other softwares I have used in past years. They also provide great support via email or live chat/video call when required at any stage during development process (I am working for them). There are minor bugs sometimes but they get fixed quickly. Go ahead with this software as nothing significant came across so far from their side except some small issues related to UI design / structure etc., we were using iOS SDK only until now and then changed over Android Studio since Android version was not supporting older versions. We had been developing applications that helps people connect online through our platforms like Facebook messenger, Whatsapp group bots & more recently launched website where users can book train tickets by just sharing location information on map.
