Gyroscope Blog comes from the team behind a personal data tracking app, with posts on React Native, web animation, and sleep detection.
HN links it for posts on how the app was built, such as April Zero and React Native, with commenters debating its React Native tradeoffs.
How "Tight to ReactJS and facebook ecosystem for React Native" is a minus but "Closely work with Google" is a positive point ? Even if ReactJS is made by Facebook engineers, I never saw integration with Facebook ecosystem in their code. Honestly the comparison is so subjective.
The plugin model of Nativescript is easier to write because you don't need to write the binding part but you're not showing all of the plugins already created for React Native. I'm pretty sure there are more for it than Nativescript.
I still didn't see good app written with Nativescript. The iOS demo in your links is so simple. Even with Ionic Framework, you can make better. For React Native, have a look to Gyroscope. https://blog.gyrosco.pe/the-making-of-gyroscope-running-a4ad10acc0d0#.mvnwbvyzb
I tried Nativescript and it's really good but I found myself more comfortable with React Native due to my ReactJS background. Like every hybrid solution, it depends on your knowledge, needs, targeted platforms, there is no absolute answer.
This is exactly the message we are trying to get across at Gyroscope.
