Apache Cordova can be a very useful tool for mobile application developers who want to extend their application across more than one platform, without having to re-implement it with each platform's language. Also, they can mix native application components with a WebView that can access device-level APIs and can also help to develop a plugin interface between WebView and the native components.
Moreover, popular apps such as Series Seven, Sprint Social, Monday delights were also made using Framework7.
