Achieve Superior Mobile Site Speed

Examples-

Starbucks- Aiming at providing accessible, user-friendly online ordering to their customers, Starbucks built a PWA of the ordering system on the web, which delivers a similar experience to their existing native app. In other words, with its capability to run in offline mode, Starbucks PWA allows their customers to browse the menu, customize their orders, and add items to their carts – all without consistent access to the internet. Once online, they can view location-specific pricing and place their food and drinks order. Starbucks provides a PWA that is 99.84% smaller than its equivalent iOS app (Native app). After deploying its PWA, Starbucks doubled the number of online orders, with desktop users ordering at about the same rate as mobile app users.

Twitter- In 2017, Twitter released Twitter Lite, a PWA alternative to the official native Android and iOS apps. Twitter Lite consumed only 1-3% of the size of the native apps. In July 2019 Twitter started serving all website users to Twitter Lite by default. On June 1, 2020, Twitter deactivated the legacy website layout, leaving the progressive web app version as the only option.

Uber- As the company expands to new markets, its Uber web was rebuilt from scratch as a PWA to offer a comparable booking experience to the native mobile app. The Uber PWA is designed to make car booking viable on low-speed, 2G networks. Built around the concept of an app-like experience which is accessible on all modern browsers, The PWA is great for riders on low-end devices, which may not be compatible with the native Uber app. By bringing the native experience in a super-lightweight web app, Uber has enabled quick ride requests regardless of location, network speed, and device. The core app of only 50kB allows it to load within 3 seconds on 2G networks.

BMW- The new BMW’s PWA delivers users a ‘wow’ experience. The first thing that anyone would notice is the high-resolution images and videos, and the web loads pretty much instantly with all these features (4X times faster than the old site). Their reports also showed other impressive numbers following the establishment of the PWA: 4X increase in people clicking from the homepage to a BMW sales site; 50% growth in mobile users and 49% more site visits compared to the old site.

Pinterest- With a focus on international growth, Pinterest started their new mobile web experience from the ground up as a PWA. The social network found that only 1% of their mobile users convert into sign-ups, logins or app installs, due to poor performance on mobile. Onto realizing that the opportunity to improve the conversion was huge, so they rebuilt the mobile web using PWA technology, which led to several positive results: Time spent is up by 40% compared to the previous mobile web, user-generated ad revenue is up 44% and core engagements are up 60%

Spotify- Your favorite music player is now PWA-powered. Due to some disagreement between Spotify and Apple regarding Apple’s 30% app store commission, Spotify found it a timely opportunity to start developing a PWA version of their app—as many other big brands have. Compared to its native-app counterpart, the PWA version is considerably faster with its own unique and adaptive UI that changes its background as the user progresses through the app. Like many other PWAs, users are also prompted to add Spotify PWA to their home screen, making Spotify PWA more accessible and on-par with its other versions.
