Answer 1

React Native app does run slower on Android. But the performance is not real during your development. You can build a release version to check the real performance, release version is much faster than dev version.

There are also some bad codes which can make your app slow. Like console.log(), it does slow the app during development. Avoid unnecessary re-render the view, don't use arrow function and .bind in render, etc.
