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 http://wiki.rhomobile.com

The Rhomobile Components

Rhodes “microframework” for building locally executing

natively optimized mobile apps Developers run app generator for their objects of

interest and then edit HTML templates Contains first mobile Ruby implementation

RhoSync Sync focused on web service data (needed in the

age of SaaS) Handles keeping your data local on the device

Rhodes Apps

Issues to Go – VDG Group (on the AppStore)Interface to public bug tracking systems such as LightHouse

PixalPedia – Carry the Day (on the AppStore)Take a picture with device camera, it geotags it, shows you map of location and retrieves Wikipedia article

On My Means – Paul Oremland Budgeting app, written in less than 40 hours by developer with no knowledge of Rhodes. Accepted by AppStore in 4 days

Wikipedia – Wikimedia (Hampton Catlin)threw away their iPhone Objective C app, rewrote it in Rhodes with 20% of code

Rho-See-Bell – Dan BikleInterface to Siebel CRM

RhoCRM – Rhomobile (to be sold to third party) Interface to SugarCRM, includes “map my accounts”, sync to local device contacts

PLUS 26 contest entries released as open source on May 24th!

Why Rhomobile?

Declarative tag-based approach (web programming) is more productive

Rich client against local data much better than remote web apps
