When to Make a Native App

• Charging for it• Creating a game• Using specific locations*• Using cameras• Using accelerometers• Accessing the filesystems• Offline users

* Actually available to web-based applications3

The Case for Mobile Web Apps

“I believe that unless your application meets one of these native application criteria, you should not create a native application, but should instead focus on building a mobile web application.”

— Brian Fling, “Mobile Design and Development”
