Mobile App Development Training Chennai

width="200"Given the current proliferation of mobile touchpoints, we are often tasked with helping clients create mobile roadmaps and strategies. Inevitably, we are asked if there is a way to build content or functionality once and deploy it on a variety of different mobile platforms. The answer, of course, is yes. In fact, there are several ways, and the benefits of doing so vary from a more streamlined development process to higher adoption rates to lower costs. However, when is the right time to use cross-platform solution? What kind of requirements lend themselves to this simpler approach? When is the cross-platform approach actually simpler than developing for native applications?

In this post, I’m going to examine some of the existing technologies for cross-platform development of mobile apps, with an emphasis on determining when they might be appropriate for an app or business and when they might not.

What are the available cross-platform tools (CPTs)?

There are many—at least 100+—of these CPTs in today’s market, though we only typically hear of a few. Those with the most usage include:

Adobe PhoneGap
Sencha Touch
Appcelerator Titanium
The most prominent of the bunch and the ones I’m most familiar with are:


PhoneGap uses HTML5 inside of a WebView on your device. It essentially creates a mobile “web app” that sits inside a native application wrapper. The web code is packaged with a library that bridges web code to native functionality. PhoneGap is open source (free) and supports iOS, Android, BlackBerry (not yet 10), WebOS, Windows Phone 7, Symbian and Bada.

Cross Vs NativePhoneGap developers report advantages—such as low barrier to entry (HTML/JavaScript/CSS is the only skill needed to get started), a single code base for all platforms and rapid testing and deployment. Reported disadvantages include poor performance—there’s only so much you can get out of a WebView on any platform—and lack of support for native UI elements and widgets. Reports indicate graphically-intensive applications are not a good fit for PhoneGap.

Appcelerator Titanium

Titanium is similar to PhoneGap (it’s free), but not exactly the same. The main difference lies in device support—it’s built to produce iOS, Android and web apps only. It actually compiles the JavaScript code into a native binary—converting the JavaScript into native class and object files—whereas PhoneGap simply renders a WebView with the code being interpreted inside.

“So, a simple way to think about it is that your JS code is compiled almost one-to-one into the representative symbols in nativeland. There’s still an interpreter running in interpreted mode, otherwise things like dynamic code wouldn’t work. However, it’s much faster, much more compact and it’s about as close to pure native mapping as you can get, ” states Jeff Haynie, CEO of Appcelerator.

Proponents of Titanium argue performance is not an issue because the app is compiled as a native app. They say using native UI elements—as opposed to PhoneGap, which creates its own—allows apps to more closely resemble the look and feel of a native app. This is probably as close as you can get to having a CPT app resemble an actual native app.
