Native vs. HTML5 vs. Hybrid
Native Applications
Pros
Feature rich, look & feel and performance
Objective-C & Java
Easy to find applications
Easy to monetize applications
Cons
Limited to single platform
Objective-C & Java
Distribution via Apple App Store and Google Play
HTML5 Applications

A "write one, run many" solution that is cross platform and cross device
Low barrier to entry - HTML5, CSS3 & JavaScript skills
Cons
Not up to par with the native app experience
jQuery Mobile
Sencha Touch
jQTouch
Hybrid Applications
Pros
Application framework that enables you to build natively installed applications using HTML,
CSS and JavaScript.
Supports accelerometer, camera, compass, contacts, geolocation, sotification, storage and
more.
PhoneGap Build – no SDKs to install! Spits out binaries for 7 different mobile platforms
Discover and monetize via App Store and Play
Cons
PhoneGap: Doesn’t look native
Titanium: Platform specific API via JavaScript for Android & iOS. No HTML or CSS support.
What Can You Build with PhoneGap?
Salesforce.com Mobile SDK

hybrid applications

jQuery Mobile - View
Super easy! Uses web standard HTML5, CSS3, and JavaScript
to easily develop user interfaces for mobile web apps
Framework built on top of jQuery – EVERYONE loves jQuery!
Provides custom events to detect mobile and touch specific
actions like tap, tap-and-hold, swipe, and orientation change (i.e.
rotating the device).
We are just building web pages!!
Database.com - Model
A secure, cloud database for building social and mobile enterprise apps.
Slimmed down version of Force.com database (essentially the Setup section)
Only custom objects (no CRUD UI)
Apex classes, triggers & workflow
Identity & user management plus role and profile security
Oauth2 & REST baked in
Utilize your favorite Force.com tools
Pricing based upon user licenses, records and transactions

Great for quickly building social and mobile applications
Leverage thousands of open source packages and frameworks to build amazing
applications.
Databasedotcom Ruby gem
Open source ruby client for accessing REST and Chatter APIs
Supports OAuth2
ActiveRecord syntax
Should be called ‘Forcedotcom’ gem
Host the application on Heroku – WINNING!
