PWA app development: install, offline, no stores

PWA app development — a Progressive Web App with home-screen install, offline use, and (where the OS allows) push — without App Store or Google Play publishing. VivaCoding in Cyprus (Paphos) ships PWAs from €1,490 in typically 2–3 weeks: faster and cheaper than native/cross-platform when you do not need Bluetooth, AR, or deep device APIs.

A PWA (Progressive Web App) is a web app that behaves like a mobile client: home-screen icon, fast cached launch, updates without store review. Technically it is an HTTPS site with a Web App Manifest and a Service Worker. For loyalty, catalogues, booking, simple orders, and B2B portals it often covers 70–80% of “app” needs without dual native builds.

Below: how a PWA differs from a site and from native, when to choose it in Cyprus, what VivaCoding packages include, iOS limits, and when React Native / Flutter is the better next step.

What PWA development means

PWA development is designing UX and shipping a web client that meets installability: HTTPS, a manifest (name, icons, display mode), and a service worker for cache and offline fallbacks. Users open a URL, add it to the home screen, and return like an app — without store search or Apple/Google review waits.

In 2026, PWAs are the budget entry to a “mobile product”: CIS market MVP ranges often sit around hundreds of thousands of rubles; Cyprus/EU studios commonly start near €1,500 for a tight scope. Dual native costs more; React Native / Flutter sits in between when you need stores and broader device APIs.

PWA vs website vs native / cross-platform

Format	Install	Updates	Device APIs	Best for
Responsive site	None	Instant	Minimal	Content, SEO, one-off visits
PWA	From browser	Instant	Medium (camera/geo partial)	Loyalty, orders, portal, MVP
React Native / Flutter	Stores	Via review	Broader	Store presence and app-like push
Native Swift/Kotlin	Stores	Via review	Maximum	AR/ML, Bluetooth, heavy offline

For the full mobile map and pricing, see mobile app development. To validate a hypothesis without “app feel”, a Lean MVP or web application may be enough.

When a PWA fits

• You need a fast MVP or repeat visits (loyalty, booking, menu, order status).
• You want install without App Store / Google Play and without store fees on web payments (Stripe, JCC, etc.).
• You have or plan one backend for the site and the “app”.
• Your team is strong in web (React/Vue) and does not want two native tracks on day one.
• URL sharing, landing SEO, and instant feature rollouts matter.

When a PWA is not the best choice

Do not rely on a PWA alone if the product needs Bluetooth/NFC, ARKit, complex background tracking, OS widgets, or you intentionally distribute only via stores and ASO. On iOS, push and true background behaviour remain narrower than native — design scenarios around that instead of promising “Instagram parity”.

PWA development packages

Prices are ranges after scope lock. The contract amount is fixed.

Package	From	Timeline	Includes
Start	€1,490	2–3 weeks	Manifest, icons, service worker, 5–8 screens, offline fallback, install UX
Business	€2,490	3–5 weeks	Start + auth, forms → CRM, push where available, basic analytics
PWA + API	€3,990+	4–8 weeks	Dedicated backend, roles, payments, media, admin

A typical package includes UX/UI, front-end build, tests on Android Chrome and iOS Safari, HTTPS deploy, a short install guide for your clients, and 14–30 days of post-launch support. Excluded: paid traffic, third-party SaaS beyond the agreed list, native store wrappers (quoted separately if needed).

How we build a PWA — 4 steps

1. Brief and installability criteria — flows, iOS/Android split, push needs, offline data, CRM link.
2. UX and prototype — key screens in Figma, path “open URL → install → return”.
3. Build — manifest, service worker, cache strategy, auth/integrations per package; staging demo.
4. Launch and handoff — production, metrics, install checklist for your team; iteration-2 plan from usage.

Technical baseline for a solid PWA

• HTTPS, correct maskable icons, display standalone/fullscreen.
• Service worker with an explicit cache strategy (shell + API) and offline fallback.
• Fast mobile LCP — no “everything in one bundle”.
• Clear install prompt / Safari “Add to Home Screen” guidance.
• Privacy policy when you use auth, geolocation, or marketing push.

FAQ

How is a PWA different from a mobile website?

A site opens in the browser without install. A PWA adds a manifest, icon, browser-chrome-free display modes, and a service worker for offline/cache. Users return like an app, not only via a bookmark.

How much does PWA development cost?

At VivaCoding: from €1,490 for a start installable contour, from €2,490 with auth/CRM/push, from €3,990 with a dedicated API. The wider market goes higher for complex PWAs; the exact quote follows the Must-have list.

Does push work on iPhone?

On modern iOS, web push exists in limited scenarios and depends on OS/browser version. On Android (Chrome) push is usually more reliable. We document what we promise for iOS clients — no silent gaps.

Do we need App Store publishing?

For a classic PWA — no. If you later need store presence, we discuss a wrapper or a separate React Native / Flutter client — a different scope.

Can we move to native later?

Yes. API and product logic often reuse; the client changes. Move to native/cross when PWA metrics prove demand and hardware or store requirements appear.

What about post-launch support?

After release — a free fix window (usually 14–30 days). Then maintenance packs: dependency updates, small features, monitoring. PWAs are cheaper to maintain than dual native, but without a budget they still age.
