Understanding Native Apps

Which of the following best describes a native mobile app?

A An app developed specifically for one platform using that platform's programming language and tools.

B An app built using web technologies like HTML, CSS, and JavaScript that runs inside a browser.

C An app that combines web code wrapped inside a native container to run on multiple platforms.

D An app that only works on desktop computers and not on mobile devices.

💡 Hint

Think about apps that are downloaded from app stores and use platform-specific features.

Native apps are created for a specific platform (like iOS or Android) using that platform's programming language and tools. They can use device features directly and usually perform best.

Identifying App Type by Behavior

A mobile app loads a web page inside a container and can run on both iOS and Android without changing its code. What type of app is this?

A Native app

B Web app

C Hybrid app

D Desktop app

💡 Hint

It uses web code but runs inside a native wrapper.

Hybrid apps combine web technologies inside a native container, allowing them to run on multiple platforms with the same codebase.

Performance Differences

Which mobile app type generally offers the best performance and access to device features?

A Web app

B Native app

C Progressive web app

D Hybrid app

💡 Hint

Consider which app type is built specifically for the device's operating system.

Native apps are optimized for their platform, providing the best performance and full access to device features like camera, GPS, and sensors.

Error Identification in App Type Description

Which option incorrectly describes a web app?

A Uses platform-specific programming languages like Swift or Kotlin.

B Can be accessed via a URL and updated instantly.

C Runs inside a mobile device's browser and does not require installation.

D Does not have direct access to device hardware like native apps.

💡 Hint

Web apps use web technologies, not platform-specific languages.

Web apps are built with web technologies (HTML, CSS, JavaScript) and run in browsers. They do not use platform-specific languages like Swift or Kotlin.

Choosing the Right App Type for a Scenario

A company wants an app that works offline, uses device camera and GPS, and provides the best user experience on iOS and Android. Which app type should they choose?

A Progressive web app, because it can be installed and work offline.

B Hybrid app, because it uses web code inside a native wrapper for multiple platforms.

C Web app, because it works on all devices through browsers.

D Native app, because it offers full device access and best performance per platform.

💡 Hint

Consider offline use, device features, and user experience quality.

Native apps provide the best user experience, full access to device features like camera and GPS, and can work offline reliably on each platform.
