Progressive Web Apps (PWAs) are the perfect blend of a website and a native mobile app. This new technology allows startups to deliver native mobile app experiences to customers quickly and smoothly, which can be built easily using basic web technologies like JavaScript, HTML & CSS. . The world’s top companies have increased their traffic, customer engagement and achieved higher conversion rates with PWAs. In this article, Tech Town will give examples of a few successful PWA companies that you can refer to or get motivated from.


With nearly 330 million users monthly using, creating, and sharing content around the world, it’s no wonder Twitter wants to keep their mobile web experience the fastest, most reliable, and most engaging it can be. body. This was the main goal when they decided to upgrade their web application to PWA.

 They were successful. Twitter Lite gave customers a better user experience and helped the company:

  •     Increase pages per second by 65%.
  •     Increase the number of Tweets sent by 75%.
  •     Reduce bounce rate to 20%.

 All those benefits require 3% less device storage space than Twitter’s native Android app. Instead of installing apps through the App Store or Play Store, users can optionally “Add to Homescreen” right from their smartphone browser.


Instagram was one of the first major companies to adopt PWA technology. They provide a social networking service for sharing photos and videos. Like Twitter, they upgraded their web app, giving users access to functions that were previously only available in the native app.

 Instagram PWA currently supports push notifications, has a web manifest and can be installed on both iOS and Android devices, using less storage space.


While there are still some navigational issues, the pros outweigh the cons in terms of user experience thanks to the app’s fast speed and lightness. According to recent news, Instagram will also expand PWA’s compatibility with Windows Mobile OS.

Alibaba is the world’s largest e-commerce platform, serving more than 200 countries and regions. After upgrading the site to a PWA, they get:

  •     76% increase in cross-browser conversion rates
  •     iOS monthly active users increased 14%; 30% on Android
  •     4x higher engagement rate from the “Add to home screen” prompt

 Alibaba released their PWA in 2016, the same year they made $15.69 billion in revenue. This number is also thanks to the PWA conversion that increased to more than 60 billion dollars by the end of 2019.

 Through understanding how users interact with the business, they were able to deliver a great user experience for both first-time and returning visitors. Their PWA can also send push notifications just like the native app, achieving the same open rates on both platforms.


Trivago is one of the world’s most popular hotel search engines. The travel industry has been heavily disrupted by the internet over the past two decades. Since their inception, they have been acutely aware that it is necessary to use emerging technologies to compete with the competition.

 The majority of users access their services via mobile phones, so mobile app development is quickly becoming a number one priority. They finally decided to design a PWA to improve the user experience.

 Since then, more than half a million users have added Trivago to their device home screen. User engagement using this function has increased by 150% thanks to push notifications. This increase in engagement also resulted in a 97% increase in clicks on hotel recommendations for PWA users.


There were 2 main reasons behind Starbuck’s decision to develop a PWA: They wanted to introduce ordering functionality on the site, while also making it more accessible to emerging markets. In this way, their service achieves availability in areas where internet connections are unreliable, such as rural communities.


Since PWA is built around the concept of “offline-first”, it is well suited for situations like Starbucks. Most PWAs are available without an internet connection. Customers can modify products according to their orders and the information is sent directly to the POS terminal.

 Starbuck now has a fast, efficient, easy to use PWA that is 99% lighter than the 148MB native iOS app. Using React, the development team was even able to integrate content-specific animations commonly found in native apps – something that is rarely seen in web apps.


Tinder was also one of the first companies to adopt PWA technology. They found that a web session was often longer than their native apps. Users frequently use the web to send messages and edit their profiles, so Tinder decided to focus primarily on improving performance and user experience on the platform.

 They chose React and Redux as their main technologies. JavaScript performance optimizations for improved load times, service workers for network resilience, and push notifications for chat interactions.

 Tinder is still iterating on their PWA and getting great benefits. They cut the load time by 61% from 11.91 to 4.69 seconds. It delivers the native Tinder experience with only 10% of data investment. PWA is also 90% lighter than their native Android app.


Low engagement rates are the driving force behind the growth of Pinterest’s PWAs. They realized that their mobile site only converted 1% of users into signing up, signing in, and installing native iOS and Android apps.

 They needed to do something to increase web engagement, and the PWA helped them. Pinterest took just 3 months to improve business metrics, users started spending 40% more time on the new PWA than on the old mobile site. This resulted in a 44% increase in ad revenue generated by users and a 60% increase in engagement.

 Performance is also greatly improved, due to the monolithic structure and some “CPU-heavy JavaScript” the old site took up to 23 seconds to load completely, this timeout was reduced to just 5.6 seconds in New PWAs.


Telegram’s PWA was “available” to competitors when WhatsApp Web hit the market. It offers almost identical features to the mobile version, and is much lighter and faster than a regular app.


Besides the usual strengths, this PWA also has a small drawback, that is, users have to register on the original Telegram app and verify details before starting to use it for the web. This is necessary due to Telegram’s high security standards. All messages are encrypted in the cloud and there is also a secret chat feature that is not stored on Telegram’s servers.


The above examples of PWA adoption demonstrate that this new type of app provides real, measurable value in both user engagement and helps companies increase profits.

 Hopefully through these real-life examples, we can inspire startups. This technology provides many opportunities for businesses of all sizes to engage more with their mobile website users and gain real benefits in terms of online loyalty and profits.
