Since many browsers are not compatible and does not follow Web standards in full, an app runs fine on desktop browser may be a mess on smart phone. i.e. an app may run fine on Chrome Windows but get troubles on Safari of iOS.
Is it good to build, integrate, bundle an open source embedded browser to distribute with meteor apps for mobile?
Crosswalk for Android is pretty much what you are talking about
I tested a MDL based app, even Google’s own Chromes for Windows laptop and for iOS iPad are different.
For Crosswalk its Windows and Android engine is Chrome but its iOS engine is MKWebView, so CrossWalk does not solve the problem. Apple does not allow use third party HTML5 engine in iOS?
