4. Native user interface
Apps are built with standard, native
user interface controls for easy and
familiar interactions
High-fidelity API access
Apps have access to the full spectrum of
functionality exposed by the underlying
platform and device
Native performance
Apps leverage platform-specific hardware
acceleration, and are compiled as native
binaries, not interpreted at runtime

for Apple’s App Store
Xamarin.Android takes advantage of
Just In Time (JIT) compilation on the Android device
