After finished projects with Kivy then i take a look to HTML5 mobile development framework.
Do i need cross platform? May be yes and may be no!
But new player is comming Swift . The first look on Swift for me is "Is it python version on native language on Apple?"
Let's first start with HTML5 mobile development framework. Then do native if it need.
