iOS and Android Widgets?

I searched a bit the web, but can’t find a proper answer, perhaps i am not asking the right questions:

Is it possible to add / create Widgets withing a hybrid app / solution?

My current project shows a dashboard to the user, and I would like to have a simplified dashboard shown as a Widget on Android and iOS (especially with iOS now also supporting Widgets on the home screen)

Any ideas where I have to look?
