Why a web app (PWA)?
On every smartphone
One app for iPhone, Android, tablet and PC – installable from the browser, with its own icon on the home screen.
Live sooner
No app store review, no waiting: updates reach all users immediately. If needed, we make the app store-ready later.
Fixed prices
Clear packages for private and business use with a fixed scope. Additional wishes are billed transparently at the hourly rate – only after your approval.
Your source code
You get the full source code and may have it developed further freely. Runs on standard web hosting or your own server.
Secure and data-minimal
Login, roles, backups and HTTPS are built in from the start – GDPR-friendly, your data stays with you.
Built from practice
We have been building our own web apps for businesses for years – the same technology goes into your app.

Frequently asked questions about web app development
What is a web app (PWA)?
A progressive web app runs in the browser but can be installed on the home screen like an app – on iPhone, Android, tablet and PC. It needs no app store, and updates reach all users immediately.
Can my app also go into the App Store or Google Play?
Yes, as an option to the Enterprise package: we wrap the app in a store-capable wrapper for iOS and Android, with offline mode and push notifications if you like – based on effort and quoted in advance. The Apple and Google accounts are in your name.
What counts as a screen?
A separate view of the app, e.g. start, list, detail page, form or settings. Login and error pages do not count.
Are the prices fixed?
The business packages Basic (from €199), Pro (from €499) and Enterprise (from €999) are starting prices. After the initial consultation you receive a fixed price for the agreed scope. Anything beyond it is quoted in advance and billed at the hourly rate of €75 – only after your approval.
What are credits?
Credits are changes after completion that are already included in the package: Private Mini includes 2, Private Plus 5, Basic 2, Pro 5 and Enterprise 10 credits. 1 credit equals one small change after go-live, e.g. a new text, an additional field, a colour or a button. Larger wishes are quoted in advance. You can get more credits on request at any time.
How long does development take?
Private Mini is often ready in one to two weeks, Basic usually in one to two weeks, Pro in two to four weeks, Enterprise in four to eight weeks depending on scope. You get the exact schedule together with the concept.
Who owns the app?
You do. You get the full source code and all rights to use it in your business – without a subscription and without being tied to us.
What does it cost to run after go-live?
The app runs on your hosting. If you like, we take over maintenance for €49 per month: updates, backups and security fixes. Private apps are maintained for €9 per month. Maintenance can be cancelled monthly.
How do I pay?
Not through the shop: after the initial consultation you receive a written quote. Payment is made in instalments based on milestones. Without your go-ahead there are no costs.
We reserve the right not to charge for service.
