Flutter vs React Native vs Native: Deep Performance Comparison

Let’s compare FPS, CPU, Memory, and GPU performance of popular mobile development tools on everyday life tasks.

The Story Behind the Research

inVerita and its mobile development team continuously dig into the performance of cross-platform mobile solutions available on the market to answer the question which technology is best Flutter or React Native(or Native) for your product, maybe even career, that’s how Flutter vs React Native vs Native Part I emerged. Yes, it was quite controversial as one can state we weren’t using React Native to perform multiple calculations daily — that might be the case — but in this case, CPU heavy tasks are better performed by Flutter or Native apps.

That’s why in this article we decided to research the performance of UI which has a much bigger impact on a daily user of mobile apps.

Measuring UI performance is complex and it requires an engineer to implement the same functionality in the same way across every platform. We went with a GameBench as a global testing tool to leave no doubts and make sure we stay objective (it doesn’t change the fact that we truly love Flutter in most aspects:) and still run lots of React Native and Native…
