I like that it is easy for non-technical people who don't know how code works, or even have not used coding at all before (as myself) can easily write an app with no programming knowledge required! It also has great support which makes things run smoothly when you need them too :) We are creating apps using this platform so we haven’t seen anything yet but from what i've heard there was nothing wrong either way - just be patient if some features take time as they will get added eventually :).
The only thing about NGAP compared other platforms out their such Appirio/Appcelerator etc would cost more money upfront because of having access rights granted by Apple / Google store approval process where one needs lots cash up front otherwise your product won;' t go live until later date without any warning given beforehand!
