Web Apps That Work Everywhere, Even Without Internet
We design and develop Progressive Web Apps that behave like native mobile applications while living entirely on the web. Clients get faster load times, offline functionality, and higher engagement without the cost of separate iOS and Android builds.
One Build, All Devices
A single PWA replaces separate iOS and Android apps, cutting ongoing maintenance effort and ensuring feature parity across every platform.
Instant Repeat Loads
Cached assets and a service worker mean returning users see your app in under a second, regardless of connection quality.
Re-engage Without an App Store
Push notifications and home-screen installation let you reach users directly without the approval delays or commission fees of app marketplaces.
Progressive Web App (PWA)
The outcome we're after
Most mobile users abandon sites that take more than three seconds to load, yet building separate native apps for iOS and Android is expensive and slow to maintain. Businesses end up choosing between speed and reach, or spending far more than they should.
At Splicity Dynamics, we build PWAs using service workers, a web app manifest, and a cache-first loading strategy so your app is reliable whether the user has full 4G or a patchy hotel Wi-Fi. We handle everything from the initial shell architecture to background sync and rich push notifications.
The result is a single codebase that installs on a user's home screen, loads in under two seconds on repeat visits, and keeps working during network outages — reducing your development overhead while improving retention rates and user satisfaction scores.

FAQ
Frequently asked questions
Will a PWA actually replace our native mobile app?
For most use cases — content apps, e-commerce, dashboards, and SaaS tools — yes. PWAs now support cameras, GPS, offline storage, and push notifications. If your app requires deep hardware access like Bluetooth or NFC at scale, we will advise you on a hybrid approach instead.
How long does it take to build a PWA from scratch?
A focused PWA with core offline functionality and a polished UI typically takes six to ten weeks, depending on backend complexity. If we are converting an existing web application, the timeline is often shorter because the core product logic is already in place.
Do PWAs rank well on Google?
Yes. Because PWAs are web-first, every page is crawlable and indexable. The performance improvements — faster load times, lower bounce rates — directly contribute to better Core Web Vitals scores, which Google uses as a ranking signal.
What happens to the PWA when a user is completely offline?
We configure a service worker that caches the app shell and any content the user has already visited. They can browse those pages, complete forms, and queue actions; everything syncs automatically once connectivity is restored. We design the offline experience as a first-class feature, not an afterthought.
