Out of the box
The process for developing a HATS mobile application is the same as developing a HATS web application; with some considerations given for mobile devices.
Differences for mobile devices:
– Screen real estate is smaller
– Input methods: Smaller keypads, touchscreens
– Less processing power

Lessons learned, recommendations, tips and techniques
No direct to native application support
Cannot convert a HATS web project to a mobile project
Target specific needs for screen customizations
Devices are different, experience is different
Depending on the target device, you may not want to use the HATS mobile project. iPad and Android tablets are better suited to a traditional HATS web project
