Flutter vs React Native , which should I choose?

Flutter is better for visually custom UIs and pixel-perfect designs. React Native is better if you already have a React web app and want to share logic. We advise based on your specific project.

Is cross-platform performance comparable to native?

Yes for most apps. The performance gap is negligible for 90% of use cases. We recommend native only for apps with intensive graphics, AR, or hardware-level features.
