Native apps are expensive
Separate iOS and Android development and maintenance doubles costs and effort. A PWA serves both from one codebase.

PWA development
Progressive Web Apps (PWAs) make your website or web app installable, fast to load and usable with a poor connection, without an app store and with just one codebase.
- Format
- Progressive Web App
- Platforms
- Android, iOS, desktop
- Benefit
- One codebase, no store
- Stack
- For example, Storyblok, Supabase & Vercel
An app experience without the detour through a store.
A PWA is a web application that installs on the home screen like an app, starts quickly and can work offline as needed. Users open it through a link without an app-store download.
I build PWAs specifically for your business: a solution that fits your users and workflows rather than a template or website builder.
Does this sound familiar?
Users do not install an app
A store download is a significant barrier. A PWA opens from a link or QR code and can be added to the home screen.
The website is slow or needs a connection
Caching and service workers make your application load quickly and remain usable with an unstable connection.
What I build
Installable web app
Your own icon, full-screen display and app behaviour on mobile and desktop.
Offline features
Key content and inputs remain available offline and synchronise later.
Push notifications
Reminders and status updates delivered to supported devices.
Login, roles & data
Secure sign-in and data storage, for example with Supabase.
Performance
Fast loading through edge hosting, for example with Vercel.
Editable content
Manage your own text and content, for example with Storyblok.
Decisions in PWA projects
PWA or native app?
A PWA is usually sufficient for bookings, portals, tools and content. Native apps make sense when store presence or deep hardware access is essential. I recommend the simplest approach that achieves your goal. See App development.
What works on iOS?
Installation and offline use work on iPhone and iPad; push notifications have limitations. I check which features you need on each device beforehand.
Custom-built
Design and technology are tailored to your brand and workflows, without off-the-shelf themes or plugins.
From idea to installable app
-
Use case & scope 1 week
Clarify users, tasks and the offline and push features needed.
-
Design & prototype 1–2 weeks
Mobile-first interface and clickable core workflows.
-
Development 3–6 weeks
Build in short steps with service workers, a manifest and integrations.
-
Testing 1 week
Device, offline and performance tests on Android, iOS and desktop.
-
Deployment & operation Ongoing
Launch, monitoring and planning the next release.
When a PWA makes sense
A good fit if
- You want an app experience without an app store and duplicate development effort.
- Your users are often mobile or sometimes have a poor connection.
- You want to reach users through links, QR codes or push notifications.
Probably not a fit if
- You only need to publish information: a website is enough.
- Store presence or deep hardware access is essential.
PWA development questions
A Progressive Web App is a web application that installs like an app, loads quickly and can partly work offline. It does not require an app store.
It depends on features, roles and integrations. I offer a fixed price for a clearly defined scope. The price calculator provides a guide.
Yes, it can be installed on the home screen and run offline. Push notifications have limitations on iOS, which we discuss beforehand.
Often, yes. After a short review, we decide whether to extend the site or rebuild it.
Usually 4 to 10 weeks for the first version, depending on scope.
