  • Mobile applications have high compatibility with hardware components such as cameras, etc.
  • Web applications have lower access to hardware components than mobile applications.
  • Web applications are not exclusively connected to system resources. Set up based on the available settings of the cloud service and connect to the database to use for any purpose.
  • Web applications are not set up according to any general rules. Meanwhile, the mobile app is set up with the mobile device life cycle, so it works faster. Therefore, users can freely install and use mobile applications through the online app store.
  • Web applications are easily accessible and shared across multiple user platforms. Compared to mobile applications, Web applications are much more accessible.
  • A mobile Web app is much more alive than an app when it comes to content flexibility.
  • The user interface (GUI) is an important element. Designing application user interface is relatively difficult because of the different screen sizes on devices and browsers. The user interface on the mobile application is controlled and limited by a number of guidelines.
  • Web applications have easier access to code than mobile applications, but are vulnerable to security vulnerabilities such as SQL injection, Site Scripting, etc. On the other hand, mobile applications are capable of hacked higher.
  • Web Apps work independently across environments and join on most devices. In contrast, mobile applications are highly scalable.
  • Both mobile applications and Web applications can exist in purchasing applications, advertising, etc.

Below is a table comparing 3 basic differences between mobile apps and Web apps:

Needs internet to work on devices. The internet is not required for access for mobile devices.
The development cost is very low but the maintenance cost is relatively high. Featured mobile apps are more expensive than web apps.
