What Are Progressive Web Apps (PWAs)?

Progressive Web Apps represent the future of mobile web experiences. PWAs are web applications that use modern web capabilities to deliver app-like experiences to users. They combine the reach of the web with the engagement of native mobile apps, offering the best of both worlds for UK businesses looking to enhance their mobile presence.

Key Features of Progressive Web Apps

Progressive Enhancement

PWAs work for every user, regardless of browser choice, because they're built with progressive enhancement as a core principle. The app gracefully degrades based on device capabilities.

Responsive Design

PWAs fit any form factor: desktop, mobile, tablet, or whatever device comes next. The interface adapts seamlessly to provide optimal user experiences across all screen sizes.

Offline Functionality

Using service workers, PWAs work offline or with poor connectivity. Users can continue using core features even when internet connection is unreliable or unavailable.

App-like Experience

PWAs feel like native apps with smooth interactions, navigation patterns, and UI elements that users expect from mobile applications.

Secure by Default

PWAs are served via HTTPS to prevent tampering and ensure that content hasn't been modified during transmission, providing enterprise-grade security.

Push Notifications

Re-engage users with push notifications, even when the browser is closed. Keep users informed and drive return visits to your application.
