On Android, KMP wins decisively: 8x smaller app size, 2-4x faster cold start, and roughly half the RAM, all due to the absence of a JavaScript runtime. On iOS, results are more balanced — startup times are nearly identical on modern hardware, but React Native uses 3-4x less memory because it delegates rendering to native UIKit, while KMP's Skia renderer keeps graphics buffers in memory. CPU usage is inconclusive on both platforms. Both implementations use framework defaults without production tuning, making this a fair baseline comparison. ## Full article daily.dev links to this article rather than hosting it.
