Progressive web app development: an app experience straight from the browser

Progressive web apps combine the best of website and app: discoverable via search engines, installable on the home screen and usable even on a weak connection.

Short & clear

PWA development produces a web application that can be installed on the home screen like an app, remains usable offline and runs on iOS, Android and desktop from a single codebase – without an app store. At Nano Concepts, lean PWAs such as calculators, catalogs or data-capture tools are possible in the Starter package from €2,500, PWAs with user accounts, offline synchronization and integrations in the Professional package from €8,000, and larger platforms in the Enterprise package, priced individually. It starts with a free initial consultation including a platform check, after which you receive a transparent quote.

Create a progressive web app: app features without an app store

Not every project needs a native app in the store. PWA development creates a web application that feels like an app: users open it via a link or QR code, add it to the home screen with a tap and then launch it full screen – without a browser bar. Content is cached, so the application loads fast and stays usable even in a dead zone.

01

Technically, this is powered by a service worker that keeps data on hand and synchronizes it in the background, plus a web app manifest for icon, name and launch behavior. On Android and in desktop browsers many app features are available; on iOS there are some limitations – push notifications, for example, only work there once the app has been added to the home screen. We advise you openly on whether a PWA meets your requirements.

02

The economic advantage: one codebase serves smartphone, tablet and desktop, updates are available to everyone immediately, and store reviews are not needed. At the same time, public content remains discoverable via search engines. If that is no longer enough later, a PWA can be packaged as a store app with tools such as Capacitor and extended with native features – so the existing work is not lost.

03

When you have a progressive web app created, you get an application that launches from a link, can be installed on the home screen and remains usable even without a stable connection. A PWA app runs on the iPhone, on Android smartphones and on the desktop from a shared codebase. For many businesses, it is therefore the cost-effective answer to the wish for an app without an app store – for example for catalogs, data-capture tools, customer areas or booking flows.

04

When it comes to the “PWA vs. native app” decision, we advise you openly. On Android and the desktop, many app features are available; on iOS there are limitations that we go through with you in advance. That's why every project begins with a platform check. After that, we develop mobile-first, test on real devices and make every version available via a link. PWA costs depend on scope; you receive the exact quote after the free initial consultation.

Scope of services

App without an app store: our progressive web app services

Installable web apps with offline mode and push – one codebase for smartphone, tablet and desktop, no app store required.

PWA feasibility check

We check which of your desired features can be implemented reliably as a PWA on iOS, Android and desktop – before you invest.

Offline strategy & synchro­niza­tion

We define which data is kept locally and synchronize changes without conflicts as soon as a connection is available again.

Installa­bility & app feel

Web app manifest, app icon, home screen and full-screen mode make sure the PWA feels like a native app.

Web push notifica­tions

Push messages for reminders, status changes or offers – with user consent properly obtained.

Performance optimization

Fast load times through caching, optimized images and lean code – measurable with tools such as Lighthouse.

Optional store wrapper

If you also want a presence in the App Store or on Google Play, we package the PWA as a store app with Capacitor.

Specializations

FAQ

Frequently asked questions about Progressive web app development

A lean PWA, for example as a calculator, catalog or simple data-capture tool, is possible in the Starter package from €2,500. We build PWAs with user accounts, offline synchronization and integrations in the Professional package from €8,000. Larger platforms are quoted individually in the Enterprise package.

Since no store review is needed, a PWA can go live directly once testing is complete. A simple application is often done in a few weeks; for more complex projects with offline synchronization we plan in milestones. We will discuss the exact timeframe in the initial consultation.

We start with a free initial consultation and a platform check on whether a PWA fits your requirements. Next come the offline concept, development with test versions via link, device testing and go-live.

A PWA is suitable when fast availability, a shared codebase and discoverability via search engines are the priority. A native app makes sense if you need a presence in the App Store or deep device features such as certain Bluetooth or background processes. We advise you based on your specific requirements.

Yes. On the iPhone, a PWA can be added to the home screen and launched full screen. Some features are limited on iOS, however, and push notifications require that the app has been added to the home screen. That's why we always test your PWA on real iPhones too.

Yes. With tools such as Capacitor, a PWA can be packaged as an app for iOS and Android and extended with native features. The store guidelines apply here – Apple, for example, expects an app to offer more than a plain website view. If needed, we plan this step in from the start.

A PWA (progressive web app) is a web application that behaves like an installed app. A web app manifest defines icon, name and fullscreen launch, while a service worker caches content so the application loads quickly and stays usable offline. The foundation is web technologies such as HTML, CSS and JavaScript, delivered over an encrypted HTTPS connection.

Often yes, because one codebase serves smartphone, tablet and desktop, and store submissions and developer accounts with Apple and Google are not needed. Updates are also available to all users immediately. We check in advance in the platform check whether a PWA meets your requirements – if you need deep device features, a native app can be the better choice despite higher costs.

Often yes. If the website is built on modern technology, we add a manifest, service worker and an offline strategy so that it can be installed like an app. For older websites, we first check whether the conversion is worthwhile or whether individual areas should be rebuilt. A prerequisite for a good app feel is that the website loads fast on mobile and is clearly usable.

On Android and in desktop browsers such as Chrome or Edge, the browser usually offers installation directly or via the menu. On the iPhone, users open the PWA in Safari, for example, and choose “Add to Home Screen” in the share menu. On request, we display a short guide in the application so your users don't miss this step.

Both are based on the same web technologies and are reachable via an address. A PWA, however, can be installed on the home screen, launches fullscreen without a browser bar, works even on a poor connection thanks to caching and – depending on the device – can send push notifications. Public content remains discoverable through search engines, just like on a website.
