App Store quality. Instant web accessibility.
Eliminate app store gatekeepers, download friction, and 30% platform commissions. SYSCON creates installable, offline-capable Progressive Web Apps that deliver desktop and mobile native performance directly through modern browsers.
Zero download friction. 100% web distribution freedom.
Every friction point in software distribution burns conversion rate. Asking a customer to visit the App Store, remember their password, wait for a 120MB download over cellular, and accept complex permissions costs businesses up to 70% of potential active users.
Progressive Web Apps fundamentally change the economics of software. A user clicks a simple web link or scans a QR code, and the application loads instantly in their browser with zero install delay. When they return, a single tap adds the app directly to their iPhone or Android home screen, opening in a standalone borderless window with offline caching and native push notifications.
Measurable business advantages of modern PWAs.
How adopting a Progressive Web App strategy drives bottom-line growth, lowers customer acquisition costs, and eliminates maintenance overhead.
Organic Search Indexing
Every screen and product URL in your PWA is fully discoverable by Google and Bing search crawlers, driving organic top-of-funnel customer acquisition.
Instant Feature Deployments
Never wait 3 days for Apple or Google review teams. Merge your code to production, and all installed user instances update automatically on their next launch.
Single Unified Codebase
Build your product once in React or Next.js. The exact same application serves desktop web visitors, mobile browser shoppers, and installed app users.
Resilient Offline Reliability
Service Workers cache your application shell and essential catalog data. Users can browse catalogs and fill out order forms without an active connection.
Re-Engagement via Web Push
Send targeted promotional offers, order updates, and urgent alerts directly to user device lock screens on iOS 16.4+ and Android with high open rates.
Optional Google Play Packaging
Through Trusted Web Activities (TWA), we can package your PWA into an official Android App Bundle (.aab) for distribution in the Google Play Store without rewriting code.
Modern web capabilities powering native-grade PWAs.
Modern W3C browser standards provide deep device integration without requiring native compilation.
Service Worker Routing
Programmable client-side network proxies intercepting HTTP requests, serving cached responses instantly, and executing background data synchronizations.
IndexedDB Storage
High-capacity transactional client-side database storing gigabytes of structured operational data, documents, and media for zero-latency local queries.
VAPID Web Push
Cryptographically signed push notifications that wake up the service worker even when the browser tab is completely closed, showing rich notifications.
Install Promotion Flow
Custom in-app install banners intercepting the beforeinstallprompt event to explain value propositions before prompting installation.
Multi-environment PWA presentation switcher.
Toggle between desktop browser view, mobile browser with install prompts, and full standalone installed window mode to see how the experience adapts.
Fine-grained Workbox caching strategies for zero latency.
Not all network requests should be cached the same way. We apply tailored Workbox caching strategies based on data volatility.
Stale-While-Revalidate
Ideal for product listings and user dashboards. Returns cached content in 0 milliseconds while fetching fresh data in the background and updating the UI smoothly.
Cache-First (App Shell)
Applies to compiled JavaScript bundles, CSS stylesheets, fonts, and brand SVGs. Assets load directly from local device cache without issuing a network request.
Network-First (Live Transactions)
Used for payment authorizations and inventory reservations. Attempts live network commit first; falls back gracefully to offline queueing if connection fails.
Simulate service worker behavior across network conditions.
Toggle between high-speed 5G, flaky subway Wi-Fi, and total airplane mode. Trigger mutations to observe how Background Sync guarantees zero data loss.
Web Push notifications on iOS 16.4+ and Android.
For years, the biggest argument against PWAs was the lack of iOS push notifications. With Apple’s release of iOS 16.4 and iPadOS 16.4, PWAs installed to the home screen have full access to the Web Push API via Apple Push Notification service (APNs).
We engineer VAPID-authenticated Web Push infrastructures that deliver badges, sound alerts, and rich interactive notifications to user lock screens whether they are on an iPhone 16 Pro, a Samsung Galaxy, or a Windows laptop.
Targeted customer messaging with over 45% click-through rates, entirely independent of native app store packages.
Best of both worlds: Web URLs + Google Play Presence
Through Google's official Trusted Web Activity (TWA) protocol, your PWA can be wrapped in a lightweight Android package (.aab) and published directly to the Google Play Store.
- Tiny binary size (typically under 2 MB)
- Digital Asset Links verification proves domain ownership
- Zero maintenance: Play Store app auto-updates with web deploys
- Supports Google Play in-app billing or direct web payment
Reach app store searchers without maintaining a separate Android codebase.
Many enterprises want the organic discoverability of Google Play without the expense of building and maintaining a distinct Kotlin/Java application.
SYSCON packages your PWA via Bubblewrap into a compliant Android App Bundle signed with your corporate keystore. When users install from Google Play, they receive the full standalone experience, while your engineering team maintains only the single web codebase.
Strategic comparison: Progressive Web App vs Native App.
We provide transparent architecture counsel to help you decide when a PWA is the right commercial choice.
| Dimension | Progressive Web App (PWA) | Pure Native App (Swift/Kotlin) |
|---|---|---|
| User Discovery | Direct URL, QR Codes, SEO Search | App Store Search Only |
| Install Friction | 1-Tap (Instant from Browser) | Multi-step (100MB+ Download) |
| Platform Commission | 0% (Keep 100% of Revenue) | 15–30% Apple & Google Cut |
| Release Cycle | Instant CI/CD Edge Deployment | 24–72 Hour Store Review Delays |
| Offline Caching | Full (Workbox + IndexedDB) | Full (CoreData / SQLite) |
Engineered for 100/100 Lighthouse PWA certification.
Every PWA we build passes strict Google Lighthouse automated audits for installability, offline availability, and performance.
