NativeScript vs. Framework7 vs. JUniversal

NativeScript enables developers to build native apps for iOS, Android and Windows Universal while sharing the application code across the platforms. When building the application UI, developers use our libraries, which abstract the differences between the native platforms.

Framework7 - is a free and open source mobile HTML framework to develop hybrid mobile apps or web apps with iOS native look and feel. All you need to make it work is a simple HTML layout and attached framework's CSS and JS files! Framework7 doesn't force you to write some custom tags that will be converted by JavaScript to something else.

The vision of JUniversal came from some guys at Nokia who possess considerable expertise both in Java and in building cross-platform apps. They built this tool to provide an elegant way to translate source code and make it useful across multiple platforms. JUniversal offers you the freedom to write your shared code in Java and then translate it to C# (available now) or to C++/Objective C++ (coming soon). You can also combine JUniversal with Google’s j2objc translator to translate Java to Objective-C for iOS.
