Have your app developed – web app, iOS and Android from one source
We build apps that work in everyday life: for your customers, your team or your partners. With their own backend, clean interfaces and AI features on request – planned and implemented by software developers from Ratingen near Düsseldorf.
- Web app, PWA, iOS & Android
- Backend & API included
- Support after launch
In short
App development at Altora means: together with you we choose the right type of app – web app, progressive web app (PWA) or native app for iOS and Android –, build the app, backend and admin dashboard with Microsoft .NET and keep supporting the app after launch. For many businesses a web app is the fastest and most affordable route because it runs on every smartphone without an app store.
What we develop for you
Web apps & PWAs
Runs in the browser on every smartphone and can be added to the home screen – no app store.
iOS & Android
Native apps for the App Store and Google Play when camera, push or offline use require it.
Backend & API
Secure server logic, database and interfaces – the foundation of every good app.
Admin dashboard
Manage users, content and data for your team in the browser.
AI features
Text recognition, assistants or automatic analysis directly in the app.
Maintenance & updates
Updates for new iOS and Android versions, security and further development.
Which type of app suits your project?
A web app runs in the browser and is instantly available on all devices. It suits bookings, customer portals, check-in processes or internal tools – and avoids building the same thing twice for iOS and Android.
A progressive web app (PWA) goes one step further: it can be added to the home screen, starts like an app and can cache parts for offline use.
A native app for iOS and Android pays off if you use device features intensively, need push notifications or want to be found in the app store. We advise you honestly which option reaches your goal with the least effort.
Case in point: ParkBook as a web app
Our own parking software ParkBook shows how capable a web app can be: staff scan QR codes, take 10 vehicle photos, report damage and collect the customer's signature – all in the smartphone browser, without installation.
How much does it cost to have an app developed?
Costs depend mainly on scope, type of app and interfaces. A lean web app with a clear feature set is considerably cheaper than a native app for two platforms with many integrations.
After a free initial consultation you receive an effort estimate with feature scope and timeline. We are happy to start with a first version (MVP) that is usable quickly and grows step by step.

Frequently asked questions about app development
How much does it cost to have an app developed?
It depends on the type of app, feature scope and interfaces. A web app with a clearly limited scope is usually much cheaper than native apps for iOS and Android. After a free initial consultation you receive an effort estimate with a timeline.
Web app or native app – which is better?
A web app runs on all devices without an app store and is quicker to build. A native app pays off with intensive use of device features, push notifications or if the app should be found in the app store. We recommend the option that reaches your goal with the least effort.
How long does it take to develop an app?
Depending on scope, a first usable version (MVP) is often possible within a few weeks to a few months. We develop larger apps in stages so you can start early and incorporate feedback.
What rights do I have to the app?
After full payment you receive a right of use for the app developed specifically for you. The details are set out in our terms and the respective quote.
Do you also handle backend, servers and maintenance?
Yes. We develop the backend with database and interfaces, take care of operation and keep the app up to date with updates for new operating system versions.
Can the app be connected to existing systems?
Yes, for example to inventory management, accounting, payment providers or your website. Interface development is one of our core services.
Do you have an app idea?
Tell us about it – in a free initial consultation we clarify the type of app, scope and the most sensible first step.
