PWA development: an installable web app instead of a store app
Companies and startups that need software on phones for customers or staff, without the effort and dependency of a store app.
Updated: 2026-10
We build Progressive Web Apps on Next.js and Supabase: one codebase for phone and desktop, installable to the home screen, with defined offline behaviour, web push and data held in Zurich or Frankfurt. Scope is set during scoping, after which a fixed price applies.
Many app projects start from the assumption that an App Store listing is required. That often doubles the codebase, ties every update to store review and forces users to install before they see any value.
A PWA reaches the same users via a link, installs like an app when wanted and updates instantly for everyone with each deployment. The key lies in three decisions made before building: which features work offline, which data may live on the device and which notifications genuinely add value.
What you get
Production-ready PWA
Next.js App Router, TypeScript, responsive from phone to desktop.
Installability
Web app manifest, icons, launch behaviour and install guidance for iOS and Android.
Offline concept and service worker
Per feature: what stays readable or capturable without connection, including sync.
Web push
Notifications with consent and clear opt-out; on iOS for installed web apps.
Backend in the EU/CH
Supabase with auth, row-level security and storage in Zurich or Frankfurt.
Handover
Code, access and documentation belong to you.
How it runs
- 01
Scoping
Clarify users, devices, core features and offline needs; check whether a PWA suffices; set the fixed price.
- 02
Concept
Agree screens, roles, data model, caching strategy and data-protection concept.
- 03
Build
Iterative development with a staging environment where users test early on their own devices.
- 04
Launch
Go-live, installability checks on iOS and Android, monitoring and handover.
Price framing
Fixed price after scoping, or a retainer for ongoing development. We name the frame after a short first call, before we start.
Indicative, not a binding quote — the frame is confirmed during scoping.

FAQ
How do we know a PWA isn't enough?
When the software needs Bluetooth peripherals, NFC, persistent background processing or system widgets. We check this during scoping, before a fixed price applies.
How do users install a PWA on an iPhone?
In Safari via 'Share' and 'Add to Home Screen'. We build short, clear install guidance into the application.
Can the PWA appear on Google Play later?
Yes, via a Trusted Web Activity. The Apple App Store requires a native wrapper with additional app-like functionality.
