Mobile Website vs Hybrid App comparison

Mobile Website App

Strengths

cheapest / easiest / fastest to develop
works across all platforms
updates are immediately available to end users
can work offline

Weaknesses

cannot use device's native hardware features
slower that native apps

What can we access?

geolocation api (GPS)
device orientation (accelerometer)
battery
web audio/video (NOT supported by majority of older browsers )

Hybrid App

Strengths

code once and deploy the app to multiple platforms
can work offline
content can be updated easily

Weaknesses

partial access to the device's native hardware features
major changes to the app will require the user to update the app

What can we access? (using PhoneGap for example)

accelerometer
camera
capture (media files using device's media capture apps)
compass
connection
contacts (devices contact database)
device (device specific info)
events
geolocation
globalization
media (record and play back audio files)

How to easily detect and redirect android and iPhone

Simple script for Android detection.

<script type="text/javascript">

if ( (navigator.userAgent.indexOf('Android') != -1) ) {
document.location = "http://www.your_url.com";
}

</script>

Lets specify Android and iPhone version.

<script type="text/javascript">

var ua = navigator.userAgent;

if (ua.indexOf("Android") >= 0) {

var androidversion = parseFloat(ua.slice(ua.indexOf("Android") + 8));

if (androidversion <= 2.3) {

window.location = 'http:/www.your_url.com';

}

} if (/(iPhone)/i.test(navigator.userAgent)) {

if (/OS [1-4]_\d(_\d)? like Mac OS X/i.test(navigator.userAgent)) {

// iOS 1-4 so Do Something

window.location = 'http://www.your_url.com';

}

</script>
