Progressive Web Apps

If you’re looking for an expert developer to build your Progressive Web Application (PWA), you’ve come to the right place!

Blueberry has completed a number of PWA projects recently for business clients to help boost user acquisition, engagement and revenue.

Introduction to PWAs

PWAs are a type of application software that is delivered via the web, built using common web technologies such as HTML, CSS and JavaScript, but intended to work on any platform – desktop, tablet or mobile – in a way that achieves the same user experience as native applications on mobile devices.

PWAs provide a high-quality user experience across multiple channels and development costs can be significantly reduced compared to building separate web and mobile applications.

PWAs are like responsive web apps on steroids; a normal responsive website is designed to fit mobile screens by readjusting the layout and hiding/showing different elements to suit a mobile viewport. PWAs, on the other hand, offer similar features to a native app and are designed to give a seamless and integrated experience.

They are published in the same way as any other web page, and they behave like normal apps when opened on a mobile: they can send push notifications, have camera support, detector support, work offline (i.e. they are independent of connectivity) and be accessible from the home screen, just like a mobile app from an app store.

They achieve this by taking advantage of major advances in modern web browsers, web APIs, and front-end frameworks to deliver great app experiences to mobile and desktop users.

Key Benefits of a PWA

A key benefit of a Progressive Web App (PWA) is that a company doesn’t need to develop a separate web application and additional native apps for iOS and Android to deliver a mobile app experience. This can reduce software development costs, since one PWA can reach users across desktop, mobile, and tablets.

PWAs are also typically easier to develop and maintain than fully native applications. They combine many of the best features of the web and mobile apps while leveraging the vast web ecosystem of plugins, APIs, and community support. Compared to traditional mobile web apps, PWAs look and feel much more like native apps, are often smaller in size, and can perform well over low-bandwidth networks — leading to faster load times and reduced device storage usage.

That said, PWAs have not fully replaced native apps as once predicted. Adoption has been strong for lightweight applications, but many companies still prefer native apps for performance, deeper device integration, and richer capabilities. For example, some businesses that initially embraced PWAs (such as Twitter Lite) have since shifted focus back to native development.

One of the limiting factors has been Apple’s Safari browser, which has been slower to implement full PWA support (such as push notifications and comprehensive offline capabilities). This has constrained PWA adoption on iOS devices.

At the same time, cross-platform frameworks like Flutter, React Native, and Kotlin Multiplatform have matured, making it easier to build near-native experiences without relying on PWAs. These frameworks allow developers to share much of their codebase across platforms while still offering access to native APIs and performance.

While earlier statistics suggested that “50% of consumer-facing mobile apps are now PWAs,” this is no longer accurate. PWA adoption has fluctuated, and their role is best seen as part of a mixed app ecosystem: excellent for cost-effective, lightweight solutions, but complemented by strong growth in cross-platform and native apps where performance and device integration matter most.

PWA Demo - SyncTimer

SyncTimer is a time tracking app that allows parents to keep track of the time spent by their kids on all their devices. Importantly, the timers are synchronised so that all the devices show the same information and all play any alarms that are set, making it impossible to ignore an expired timer.

SyncTimer works directly in the browser, or can be used as a PWA. It’s hosted on an Amazon S3 server and utilises AWS Amplify (Amplify is a wrapper around other technologies), and AWS AppSync to store the data.

  • A parent can extend a timer, and the app prompts for the number of minutes extension. This is immediately visible on other devices and will silence the alarm. When the parent extends a timer, it appears as 20+10 minutes on the list and the extension is recorded in history.
  • A parent can also add a new timer to the screen or remove an existing one.
  • There is also a history view that shows what has happened so far.
