5 Main Differences Between Web Apps and Native Apps

When considering development of a mobile app, one thing you must decide is whether the app will be web based or native. In this article, I'll explain the differences between these two options.

A web app is an application or program that you access through the browser on your phone or tablet. It is different from a native app in that you don't need to download anything to your phone in order to use it. You simply access or connect to the web app, purchase if required, and away you go. Think of it as going to a web site to play a game or watch a video; you don't actually download and install the game or video onto your computer, but instead play the game or view the video online.

A native app is an application or program that runs on the device itself. An example of this would be camera apps, GPS apps or games. Native apps are downloaded and installed on the device and accessed by tapping the app icon.

Interestingly enough, when the iPhone was created, the intent was for developers to create web based apps that would run through the Safari browser included with the phone. It wasn't until hackers figured out how to crack the iPhone's codes and develop their own native apps, that Apple decided to get on board with native apps. It was at that point, that Apple also created the App Store making it incredibly easy for consumers to find and purchase apps, leading to "an explosion in downloads over its platform, and permanently transitioned the gravity of mobile app distribution away from the 'walled gardens' of mobile carriers to the app-store environments of handset manufacturers. " (from Mobi Thinking)

Of course a Web App is not to be confused with another commonly used term: Mobile Web Site. A mobile web site is a web site that can be viewed properly on a mobile device. Have you ever tried to browse the Internet on your device and end up having to scroll to the left and right, up and down so that you can view the entire site? Frustrating! Mobile web sites are specifically designed for viewing on a mobile phone or tablet. Many companies are starting to include mobile web sites as part of their online portfolio. They will have one web site for viewing on a computer and their mobile web site, essentially the same web site adjusted for viewing on a mobile phone or tablet.

Below, we've summarized 5 of the main differences between web apps and native apps:

1. Purchasing

Native apps are purchased through an online store like the Apple App Store for iPhone and iPad users or the BlackBerry App World for BlackBerry users. Web Apps are purchased via subscription or some type of pay store on the web site where the app is hosted. Making apps available at the app stores also means that if you are trying to sell an app, the purchasing portion is all taken care of and you don't need to worry about working this functionality into your web site.

We should also consider the point, of course, that there is an application process to list your native app in the Apple App Store, and that not all apps are accepted. BlackBerry's App World, however, does not have an application process making it much easier to list a blackberry app.

2. Compatibility

If you want your app to be used on all devices, a native app will need to be developed for each device, whereas since a web app is accessed through a browser, it can essentially be viewed and used on all devices.

3. Updates

Since web apps are controlled at the server level, developers can update the web app at any time ensuring that all users have the most recent version of the app. Native apps on the other hand, require users to update manually.

4. User Interface

The user experience is much richer with native apps. Graphics are installed with the app and download speed during use does not need to be considered when developing. The graphics used for web apps are not as slick user interface on a web app is somewhat limited but is getting better.

5. Functionality

Web apps cannot use all of the built in hardware on your phone or access internal data. For example, web apps cannot:

Utilize the camera, accelerometer, GPS

Place a phone call, send a message, send a text

Access photos, video, contacts, calendar, messages or email

Native apps have the ability to utilize all of the information stored on your phone and all of the phone's hardware features.

The requirements for your idea will help to determine whether or not a web or native platform is most suitable.
