Integration of Smart Watch (Android & Apple) in the Ionic Framework

I've been working on the Ionic Framework since a few months, I also checked out the new Ionic 1.0.1 version. Actually I am asking this question regarding creating a smart watch app in ionic framework.

So far I have googled and I just found this cordova plugin that interacts with the Apple watch https://github.com/20steps/cordova-plugin-watch . This is iOs support only.

There are several cordova plugins, but I haven't found a suitable answer or tutorial or blog that I can use to learn smartwatch integration. In native this task is easy, but using the same plugin and target both apple and android smart watch is more important and the cost will be less for development.

Any help for this topic would be helpful. Thank!
