Definition of Progressive web app (PWA)
What is a progressive web app?
A progressive web app (PWA) is a website that offers a native app-like experience, leveraging mobile device features without users needing to download from an app store. PWAs are designed to provide seamless, offline-capable functionality.
Who uses progressive web apps?
A variety of companies and industries use progressive web apps (PWAs) due to their flexibility, improved user experience, and cost-effectiveness. Here's an overview of who uses PWAs:
- Google recognized the potential of PWAs and launched a lightweight version of their popular Google Maps service. Before this, the main drawback of traditional map apps was their slow loading times and high data consumption. The PWA addressed these issues, providing a faster and more efficient experience.
- Also, Google Drive offers PWA versions to give users easy access to productivity tools without downloading an app.
- As an early adopter of PWA technology, Facebook relaunched its platform in 2019. The PWA provided users a viable alternative to the native mobile app, offering a more efficient and streamlined experience.
- While The Weather Channel offers a native app, a significant portion of its audience (50%) still relies on its mobile website. Many users reported difficulties accessing weather information due to poor network connections. The organization implemented a PWA to address this, ensuring reliable weather updates even in low-connectivity areas.
- To enhance accessibility and maintain the platform's appeal, Telegram developed a PWA. This expansion allowed users to access messages seamlessly across various devices while preserving the core features that made Telegram so popular.
- Coursera has implemented a PWA that allows students to access courses and videos on the go, even without an internet connection. Coursera's mobile users highly value this offline learning feature. Learners can download videos, readings, and even quizzes for offline access, making it easier to continue studying in areas with poor connectivity or to save on mobile data.
What are pros and cons of PWA?
Progressive web apps combine the features of both web and native apps. While they offer many advantages, they also come with limitations. Here is a brief overview:
Pros of PWAs:
- Cross-platform compatibility — PWAs work across multiple devices and operating systems.
- Offline access — Users can interact with the app even without an internet connection.
- No installation required — They can be added to the home screen without going through app stores.
- Lower development costs — Developers only need to build one version that works on web and mobile.
Cons of PWAs:
- Limited device integration — PWAs have restricted access to some device features compared to native apps.
- Performance — PWAs may not match the speed and responsiveness of native apps.
- App store visibility — PWAs don't benefit from app store distribution channels.

- Example: A visual support feature where customers can send photos of their issue for quicker assistance.
AR/VR projection
- Enable users to visualize products in their environment through AR/VR, providing a more realistic and engaging shopping experience.
- Example: Allow customers to virtually try on clothes or see how furniture would fit in their home.
Geolocation
- Use location data to deliver tailored content, recommendations, and store locator information.
- Example: In-store pickup options with real-time tracking and location-based promotions.
Push notifications
- Keep users informed with timely orders, promotions, and personalized recommendations updates.

- Example: Allow users to search for products, place orders, and get customer support using voice commands.
By leveraging these PWA features, businesses can create more engaging, personalized, and accessible customer experiences.
Key Takeaways
- A PWA is a web-based application that mimics the experience of a native app. It can be accessed via a browser but offers native app-like features such as offline access, push notifications, and home screen installation without needing an app store download.
- PWAs are widely used by companies like Google (for Maps and Drive), Facebook, The Weather Channel, Telegram, and Coursera.
- They combine the features of both web and native apps, offering cross-platform compatibility, offline access, and seamless user experiences without the need for app store downloads. While PWAs offer many advantages, such as lower development costs and ease of access, they also come with limitations like restricted device integration and reduced performance compared to native apps.
- With advancements in mobile technology, PWAs are expected to integrate more deeply with device features, such as push notifications, geolocation, and camera access. They hold great potential for businesses looking to enhance user experiences at a lower cost while still delivering high functionality. The continuous evolution of web capabilities and the growing adoption of PWAs by major companies suggest that PWAs will play an increasingly important role in mobile development.
