Native vs. Web
04/08/23 9
Native vs. WebCategory Native app Web app on mobile
Internet access Not Required Required in most cases.
UI Fast, Responsive and functional
Can be clunky, but new advancements are catching up fast
Streaming media
Supported Requires Plugin/HTML 5
Access to hardware sensors
Yes, all of them: camera, gyroscope, microphone, compass, accelerometer, GPS
Limited access, though geo-location is common.
Development Specific tools required and have to build a new app for each target platform
Write once, publish once, view it anywhere. Multiple tools to choose from. (jQuery for mobile)
Distribution App stores require approval which delays the release
No such hassle
Market One store where all apps are published and payment processed
You need to process payments and market your apps.

Web Native
HTML/Javascript
• These are the same technologies you will use to build any web site
• HTML5 could be a great option here especially for videos on iOS & Android
04/08/23 13
HTML/Javascript - Pros
• Industry standard – No proprietary technology• Proven technology for over 15 years• One of the largest developer pool• The largest reach - target almost all platforms• Thin client model – easy deployment• No approval process required• No Revenue sharing04/08/23 14
HTML/Javascript - Cons
• Network dependent in most cases – Web Server needed.
• Inconsistent across browsers• UI not as responsive and robust • No single marketplace• Bandwidth is getting expensive & limited
04/08/23 15
HTML/Javascript – Audience
• Apps which might not meet all certification requirements
• Apps that need to target all platforms without investing the time & money on other technologies
• An add-on bonus to the native app - We have this for everyone & native for iPhone/Android
04/08/23 16
jQuery Mobile• A Framework to build web based mobile apps • An extension of jQuery for touch based
applications
04/08/23 17
jQuery Mobile - Pros• A lightweight framework• Consistent across browsers & devices• Supports flexible, easily themeable design
giving a professional look to your app. • Supports wide range of devices and OS.• Significantly speeds up development as
compared to traditional web development.• Based on Industry standards - HTML/Javascript• Could be tested on a desktop w/o any emulator• No Approval process / Revenue sharing
04/08/23 18
jQuery Mobile - Cons
• New technology – currently under 1.0 Beta 3• Network dependent in most cases – Web
Server needed• UI not as responsive and robust • No single marketplace• Bandwidth is getting expensive & limited

jQuery Mobile – Audience• Mobile apps which looks close to native ones
and consistent across devices.• Apps which might not meet all certification
requirements• Apps that need to target all mobile platforms
without investing the time & money on other technologies

non UI related functions from WP7)• Access all platform specific features• Based on .NET – Largest developer pool• Large portfolio of popular apps• Increased performance as compared to Web
based solutions like jQuery & Phonegap.• Monodroid integrates with Visual Studio.
04/08/23 30
Mono Touch/Droid - Cons
• No single code base for – Mono Touch/Droid• Delay in access to new platform specific feature• Significantly larger package size deployed• From Novell to Xamarin • Monodroid is in early stage and is not growing at
the pace of MonoTouch• No Visual Studio / Windows support for
MonoTouch. You need MonoDevelop on Mac
04/08/23 31
Mono Touch/Droid – Audience• .NET Developers who wants native app w/o
need of learning a new platform/technology• Simple smaller Apps that could share some
code from previous .NET code especially WP7 app.
• Enterprise mobile apps in companies which has .NET resources and would like to leverage that.
• Small businesses that has only .NET resources and focused on simpler smaller apps
04/08/23 32
True Native • iOS - Objective C, Xcode, Cocoa Touch• Android - Java, Eclipse• WP7 - Silverlight, C#, Visual Studio
04/08/23 33
Native Pros• Closest to the OS• Access all platform supported features• Best Performance• Smallest package size to be deployed• Best possible UI Experience• No fear of rejection by App stores in future• Low registration cost and most of the SDK/tools
are FREE• Good level of support (included in registration)
04/08/23 34
Native - Cons• No single code base/reusability across platforms• Development time doubles with every new platform
the app targets which results in increased cost• Increased learning curve as every platform supports a
different technology/language – most of them being proprietary.
• Difficult to share developer resources thereby demanding separate developer pool for every platform.
04/08/23 35
Native – Audience• Developers/Businesses who are serious about
getting into the mobile app space• Best quality apps with high performance• Complex/Large apps which demands for a
