What are Progressive Web Apps (PWAs)?

Progressive Web Applications (PWAs) are web-based applications that leverage modern web technologies to provide an app-like experience. They can be installed on a user’s device and accessed offline, blurring the line between web and native apps. PWAs offer cross-platform compatibility and are capable of adapting to various devices, therefore, eliminating the need for separate native app development.

Explained simply, a progressive web app (PWA) is a website that looks and behaves like a mobile application. They are built to allow users access to most of the features a mobile app provides without requiring the end user to download and install an application. Instead, PWAs can be found through search engines and accessed immediately via a browser.

They make use of standardised technologies and run in a secure container that is accessible to everyone on the web but leverage push notifications, work offline and can be added to the mobile device home screen just like traditional mobile applications.

Hybrid Apps

Hybrid apps are a combination of web technologies (HTML, CSS, JavaScript) and native components. They are built using frameworks like Apache Cordova (PhoneGap) or React Native. Here are the key characteristics of hybrid apps:

Cross-Platform Development

Hybrid mobile applications allow developers to write code once and deploy it across multiple platforms, such as iOS and Android. This saves development time and effort compared to building separate native apps.

Native Capabilities

Hybrid apps can access device-specific features and APIs through native plugins. This enables them to utilise functions like camera, geolocation, and accelerometer, providing a native-like experience.

App Store Distribution

Hybrid apps can be published in app stores, making them easily discoverable and downloadable by users. They benefit from the distribution channels and visibility provided by app stores.

Performance Limitations

Hybrid apps rely on web technologies wrapped in a native shell. While they can achieve good performance for most use cases, they might not match the level of performance and responsiveness offered by fully native apps.

Native Apps

Native apps are developed specifically for a particular platform or operating system, such as iOS or Android. They are built using platform-specific programming languages (Swift/Objective-C for iOS, Java/Kotlin for Android). Here are the key characteristics of native apps:

Optimal Performance

Native apps are designed to leverage the full capabilities and performance of the underlying platform. They have direct access to device-specific features and APIs, resulting in smooth and responsive user experiences.

Enhanced User Experience

Native applications can provide a highly tailored and optimized user experience. They follow platform-specific design guidelines and integrate seamlessly with the device’s interface, leading to a familiar and intuitive user interface.

App Store Distribution

Native apps can be distributed through official app stores, allowing users to discover, download, and update them easily. App stores provide a trusted environment for users and offer various promotional and monetisation opportunities for developers.

Platform Limitations

Native apps are limited to the platform they are developed for. Building separate apps for different platforms can be time-consuming and costly. Additionally, maintaining and updating multiple codebases may require more resources.
