Mobile App vs Web App: What’s the difference?

By Shormistha Chatterjee, Community Contributor -

Mobile apps and devices have become a fixture for billions of people. 

  • In 2022, mobile internet users hit more than 5 billion, specifying that 63.1 percent of the global population uses mobile internet to go online
  • Internet usage and mobile ownership are estimated to keep rising in the future as mobile technologies are becoming more accessible and affordable than ever. 
  • The rise in the internet traffic percentage on mobile has impacted desktop web traffic. But some businesses still rely on web apps for personal and business use.‌

Technologies for both mobile and web apps are progressively evolving. Hence, companies fall into the dilemma of choosing the accurate medium to reach niche audiences. And their ultimate goal is to deliver optimal bug-free user experiences

Thus, the question is, should businesses invest in developing a mobile app, or should they focus their resources on developing a web app that is entirely user-friendly and mobile-responsive? It is the classic debate on Mobile App vs Web App.

So, let’s examine the core distinctions between mobile and web apps.

What is a Mobile Application?

Mobile applications are software programs built for a specific platform like tablets, smartphones, and other touch devices. 

  • They are downloaded via App Store (iOS) or Play Store (Android). 
  • They offer users similar functionality to what they receive while browsing a web application from a desktop computer. 
  • Some popular mobile apps are Instagram, Zoom, Snapchat,, and Spotify
  • Android and iOS are leaders in the Mobile Application domain, followed by Microsoft.

Most companies focus first on development and mobile app testing for Android and iOS and then target the rest platforms. This is due to the broad user base for Android and iOS in the global market covering around 71% and 28%, respectively (2009-2022).

But, the constant proliferation of mobile devices and other gadgets with diverse configurations required mobile apps to be well-tested across several mobile devices. To meet this demand, businesses have started incorporating best practices for mobile app testing as a complete testing strategy. 

Regarding mobile testing strategy, testing on real devices is irreplaceable. QA engineers can seek cloud-based test solutions that offer real browsers, devices, and OSs if they can’t access or invest in a device lab.

Types of Mobile Applications 

A broad dissimilarity of Mobile Applications can be made into Native & Hybrid mobile applications.

Native Mobile App

  • Mobile apps created for a niche platform (iOS or Android) )using the platform-centric SDK (software development kits) are categorized into Native Mobile Applications. 
  • Compatibility and performance with the underlying hardware like the camera, GPS, phone, network connectivity, etc.

Hybrid Mobile App

  • Hybrid Mobile applications are designed and developed on platforms that will offer you code-compatible with all accessible OS’s. 
  • Because of a single code base, Hybrid apps are popular among SMEs and Startups as it helps them create a universal app experience.
  • The most popular Hybrid application development platforms are – Flutter, Ionic, and React Native.

More so than ever, testing Progressive Web Apps (PWA) is the future as they work on any web browser on desktop and mobile devices. They are written in JavaScript, HTML, and CSS. 

How are Mobile Apps Built?

Mobile apps are more costly to develop than web applications and are platform-centric. 

Generally, a mobile app across distinct platforms means starting from scratch concerning design & development. However, they are faster and highly advanced in terms of functionality and features. 

  • Native mobile apps are built using precise languages and IDE (Integrated Development Environments), depending on the intended platform.
  • Apple gadgets run on the iOS native OS, so Apple applications are built using either Swift or Objective-C and the Xcode IDE. 
  • Native Android appls are written in Java and are generally built via Eclipse IDE or Android Studio. 
  • Google and Apple also provide their development interface elements, tools, and SDKs, which developers can employ to build native mobile apps.

When to Build a Mobile Application?

Select a mobile application when:

  • If you wish to send push notifications to your users,
  • Users will access your application numerous times a day,
  • You care about higher performance,
  • You require access to specific phone native features,
  • People will sometime use your product offline,
  • Your product includes location-based or navigation elements.

Most Common Mobile App Testing Frameworks 

  • Appium
  • XCUITest
  • Calabash
  • EarlGrey
  • Selendroid
  • Espresso
  • Robotium

Before testing mobile apps, the QA engineer needs to identify whether the app to be tested is a hybrid, native, or mobile web. Below are some mobile app testing frameworks that can be used to execute automated testing for native, hybrid, and mobile web apps.

Testing FrameworksAppiumEspressoXCUITest
About the FrameworkBased on Selenium, Appium is the most liked for testing native, hybrid, and mobile web applications. 

Appium also allows testers to select the programming language to work with.

Developed by Google, Espresso is yet another preferred native open-source framework for automated UI testing of Android apps. 

Espresso is a component of the Android SDK and is utilized for native mobile app development. 

XCUITest is a reliable UI test framework bundled with the XCode IDE. 

It enables QA engineers to automate UI testing for native iOS applications.

However, as the gatekeeper of any product, QAs must test the product on real devices, and browsers before launch. With, teams can access 3000+ real Android/iOS devices and browsers for manual and automated testing.

What is a Web Application?

A web app is self-sustaining software that entirely runs on the web browser and is highly adaptive to any device.  

  • Since web apps are not native to any system, they do not need to be installed or downloaded.
  • Web apps can span over manifold pages or be restricted to an individual page. 
  • It minimizes the overall development efforts required, contrary to writing code that requires to be migrated over various platforms. 

Office 365 from Microsoft and GSuite from Google are prominent examples of web apps that are used widely.

How are Web Apps Built?

Web apps tend to be built using CSS, HTML5, and JavaScript. Unlike mobile applications, there is zero standard software development kit to build web apps. But, software developers do have the right to access some templates. 

  • Compared to mobile apps, web applications are usually faster and simpler to build — but they are much more accessible in terms of features. 
  • An emerging trend, PWAs (progressive web apps) take benefit of recent browser advancements to enable web apps to act more like mobile applications. 
  • However, OS support and functionality are still limited compared to true mobile apps.

When to Build a Web App?

Decide to build a web app when:

  • You wish to reach a broader audience
  • You care about the development speed
  • Your audience is present more on PCs or desktops
  • You plan to upgrade and enhance your application often,
  • You wish to launch rapidly after the end product is ready.

Most Common Web App Testing Frameworks

When it comes to web application testing, a QA team can choose from:

Even though numerous commercial tools exist, Selenium has been the most popular and preferred tool suite among the QA world for years. 

  • It enables QAs to automate website UI testing across common web browsers such as Safari, Google Chrome, Firefox, etc. 
  • QAs can also implement parallel testing across desired environments using a Selenium Grid. 
  • Moreover, QAs can also simulate mouse and keyboard inputs using Selenium to simulate end-user actions.

Mobile App vs Web App: Differentiation

Let’s take a look at the core differences between mobile app vs web app

Mobile AppsWeb Apps
Need to download via an appropriate app store, which makes them less accessible to users.Web applications are accessible instantaneously on browsers.
Flexible User interfaces and support complicated functionalities.Can’t support complicated functionalities.
Patches/ Updates need to be downloaded from Play Store.Updates/ Patches are applied straight to the entire web app.
Developers have to write code targeting a particular hardware or platform.Developers do not need to cater to the underlying platform.
The monetization strategy of mobile apps is still developing.Monetization of web applications is simpler.
While mobile application needs installation, they give faster navigation with shorter load times by obtaining the system’s resources.Web application speed can depend on the internet connection quality, with poor connectivity leading to failing to load or extended loading times.
The build cost for mobile apps is higher than a standard web application.The development cost for web apps is lesser than a common native mobile app.
Mobile app tests refer to testing an app across multiple mobile devices.Web app tests focus on validating the functionality and appearance of sites across numerous browsers.

Although the testing techniques and tools used for both differ drastically, there are definite tests that are common for both:

  1. Compatibility tests
  2. Performance tests
  3. Functional tests
  4. Localization tests
  5. Usability tests

Mobile App vs. Web App: Choosing the Right One

It is challenging to pick a clear winner in the debate for mobile application vs web application.

  • Both mobile and web applications provide a better experience to the user in terms of delivering solutions.
