Native Performance

Xamarin.iOS does full Ahead Of Time (AOT) compilation to produce an ARM binary for Apple’s App Store.

Xamarin.Android takes advantage of Just In Time (JIT) compilation on the Android device.

Which Xamarin approach is best for your app?

Xamarin.Forms is best for: Xamarin.iOS / Xamarin.Android is best for:

• Data entry apps

• Prototypes and proofs-of-concept

• Apps that require little platform-specific functionality

• Apps where code sharing is more important than custom UI

Learn more: xamarin.com/forms Learn more: xamarin.com/platform

• Apps that require specialized interaction

• Apps with highly polished design

• Apps that use many platform-specific APIs

• Apps where custom UI is more important than code sharing

The future of apps

Monitoring your app in real time

Is my app crashing? What features are popular?

Does it perform well?

How many people are using it?

What countries are users in?Do users stick with the app?

What devices are they using?

The future of apps

We wouldn’t have caught the bugs as early as we did without Xamarin Insights. No other suppliers offered the kinds of benefits we’ve seen from Xamarin. The ability to trace a user journey so we can see exactly what led up to an issue and receive detailed information about crashes has been tremendously helpful.”
