Rhomobile Mission Mobilize applications rapidly with a great user experience
Provide the high level productivity and portability of web programming
Device optimization and offline capability of “native mobile apps”
Open source for rapid adoption by developers

Background
Smartphone sales are exploding
Five major smartphone operating systems: iPhone, BlackBerry, Windows Mobile, Symbian, Android
Growth leaders are installed base laggards
“ native apps” have won the day
1 billion iPhone app downloads on a platform with great browser installed (as of April 23, 2009)
But …how do you write an app for all popular devices?

A Better Way… Rhodes
Build the app quickly in HTML and Ruby
Write it once and it runs on all smartphones
Work with synced local data
Exploit device capabilities (GPS, PIM data, camera, SMS)
Available open source realtime:
http://www.github.com/rhomobile
gem install rhodes
