Businesses need to
rapidly appify with
high-quality apps
Mobile development – for
just one app – involves many
stages

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.
Create UI with drag & drop
simplicity
Target multiple screen sizes,
resolutions and Android
versions
Layouts saved in standard
Android XML files
Multi-Touch Enabled
Super Fast
Rotate, screenshots,
location changes, and
more!

What if we didn’t have to write this code?
What if we could access it from shared code?

Xamarin Live Inspector
Rapid Design Experimentation
Live Inspector and Workbooks allow developers to
programmatically interact with a running app in real-
time on devices and emulators.
Live Inspector enables rapid design experimentation
and iteration, without the need to compile, build and
deploy each time you make changes.
Xamarin Profiler
A Full-Featured Profiling Tool
Profiler is a profiling tool made specifically for Xamarin
apps, which helps developers quickly identify memory
and performance issues.
Unlike native SDK profilers that can only reveal problems
at a lower level, the Xamarin Profiler provides analysis
of code running in the Mono runtime, where Xamarin
app code lives and executes.
Xamarin Test Recorder
Effortlessly Create UI Test Scripts
Simply and quickly generate UI test scripts by running
your app and performing actions. You can execute UI
tests locally in the emulator or on thousands of devices
simultaneously with Xamarin Test Cloud.
