DUAL-UX is a runtime that lets a single Progressive Web App deliver two distinct user experiences based on context: a Web UX for discovery and an App UX for engagement—without splitting the codebase.

How does Dual-UX detect Web vs App?

It uses standards-based display-mode detection and lifecycle signals to switch views at runtime, mapping browser contexts to a Web UX and standalone/installed contexts to an App UX.

Is DUAL-UX open source?

DUAL-UX is released under a dual-license: GNU AGPL for open projects and a commercial license for enterprises that need proprietary use, support, and feature guarantees.

Product and platform teams that want the reach of the web and the retention of installed apps—ecommerce, hospitality, fintech, media, and brand-led experiences.

Why Dual-UX Beats One-Size-Fits-All

We collapse web and app into a single, continuous experience—one that adapts as user intent deepens, without forcing a moment of friction or choice.

This is not about replacing native apps. It’s about changing when the experience upgrades.

The most effective digital brands now operate on a simple principle:
When users commit, the experience should change—without them noticing the handoff.

The Marketing Advantage

It allows marketing teams to stop selling “apps” and start delivering continuity—from first interaction to long-term engagement—on the open web, at global scale, with measurable outcomes.

The curious and the comitted

The next wave of growth comes from recognizing the moment commitment happens—and upgrading the experience without asking permission.

The result: acquisition without sacrificing engagement—and a single codebase your team can ship weekly.

The two distinct operational modes are:

Web UX Mode: This experience is triggered when a user accesses the website through a standard URL in a mobile browser. The design is explicitly tailored for discovery and initial contact, functioning as an "SEO-optimized, sharable microsite with fast-loading, link-first design".

In this mode, the technology prioritizes metrics crucial for top-of-funnel user acquisition: fast initial load times to reduce bounce rates, search engine crawlability for organic discovery, and simple shareability via links, QR codes, or SMS.

App UX Mode: This experience is activated only after a user has chosen to add the website to their device's home screen. Upon launching the installed icon, the website transforms into a "full-screen, install-only experience with native-style features".

This mode is engineered to foster deep user engagement and retention, mimicking the immersive feel of a native application. Key features include dedicated onboarding flows, support for gesture-based navigation, advanced offline caching strategies, and persistent UI elements like navigation bars.

The DUAL-UX technology is designed to seamlessly switch between these two modes based on the context of use, ensuring that users receive the most appropriate experience for their current interaction. This dual-mode capability not only enhances user satisfaction but also optimizes the website for both acquisition and retention, addressing the critical challenge of balancing these two often conflicting goals in mobile app development.

Why Dual-Experience Beats One-Size-Fits-All

DUAL-UX maps context to experience: a fast, shareable Web UX in the browser and a fullscreen App UX when installed—no duplicate code, no forks.
