Looking for a way to boost user acquisition, engagement, and revenue for your business? Consider a Progressive Web App (PWA) developed by Blueberry. PWAs provide a high-quality user experience across multiple channels and are becoming a significant player in the mobile app market!
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.
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.
A key benefit of a Progressive Web App (PWA) is that you don’t need to build and maintain separate web and native apps to deliver a high‑quality experience across devices. A single PWA can run on desktop, tablet and mobile, which can significantly reduce development and maintenance costs compared to supporting multiple native codebases.
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 content‑driven sites, e‑commerce, and internal business tools, where quick access, cross‑device reach and lower development costs matter most. However, many companies still favour native or cross‑platform apps for high‑end consumer products, where performance, deep device integration (camera, sensors, Bluetooth, NFC, etc.), and richer capabilities remain critical.
Historically, one of the limiting factors was Apple’s Safari browser, which was slower to implement full PWA support (such as push notifications and comprehensive offline capabilities). Support on iOS has improved in recent years, with service workers, offline caching and installable experiences now available – but PWA capabilities on Apple devices are still more restricted and subject to change than on platforms such as Android/Chrome. This continues to influence PWA adoption where the audience is heavily iOS‑based.
At the same time, cross‑platform frameworks such as Flutter, React Native and Kotlin Multiplatform have matured, making it easier to build near‑native experiences that run on both iOS and Android from a largely shared codebase. These frameworks are often the right choice when app‑store presence, tight native API access and high performance are priorities, while PWAs excel when you want a web‑first, installable experience without app‑store friction and with a single codebase across desktop, tablet and mobile.
Earlier industry commentary suggested that a very high proportion of consumer‑facing mobile apps would become PWAs, but this hasn’t materialised in practice. Today, PWAs sit alongside native and cross‑platform frameworks as part of a mixed app ecosystem: they are excellent for cost‑effective, installable, web‑first solutions, while cross‑platform and native apps remain the default for products that demand maximum performance, rich native features and strong app‑store presence.
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.
