Web Application

A Web Application aka web-based application is any program that is accessed over a network connection using HTTP, rather than existing within a device’s memory. Web-based applications often run inside a web browser. However, web-based applications also may be client-based, where a small part of the program is downloaded to a user’s desktop, but processing is done over the internet on an external server. Web-based applications are also known as web apps.

Mobile Apps Vs. Web Apps

Native mobile apps are built for a specific platform, such as iOS for the Apple iPhone or Android for a Samsung device. They are downloaded and installed via an app store and have access to system resources, such as GPS and the camera function. Mobile apps live and run on the device itself. Snapchat, Instagram, Google Maps and Facebook Messenger are some examples of popular mobile apps.

Web apps, on the other hand, are accessed via the internet browser and will adapt to whichever device you’re viewing them on. They are not native to a particular system, and don’t need to be downloaded or installed. Due to their responsive nature, they do indeed look and function a lot like mobile apps — and this is where the confusion arises.

Let’s consider the Yelp native app vs. the Yelp.com web app. If you install the Yelp app on your mobile and then access Yelp.com via the browser on your phone, you’ll notice that the web app has been made to look and feel like the native mobile app: it turns your browser bar red, and when you scroll down, locks the search bar in place.

While the designs are similar and follow the same fonts and colour scheme, these are essentially two different products.

Web apps need an active internet connection in order to run, whereas mobile apps may work offline. Mobile apps have the advantage of being faster and more efficient, but they do require the user to regularly download updates. Web apps will update themselves.

Above all, mobile apps and web apps are designed and built very differently. To further differentiate between the two, it helps to understand how each is developed.
