Our apps start at €10,000.

Where your app needs to run makes the biggest difference.

  1. 01

    Web app from €10,000

    Runs in the browser on any device, without an app store. Often the best starting point for customer portals and team tools.

  2. 02

    Cross-platform from €20,000

    One app for iPhone and Android, built from one codebase. The usual choice if your app needs to be in the stores.

  3. 03

    Native app from €30,000

    Built specifically for iOS or Android when your app needs close access to the device, such as its camera, Bluetooth or sensors.

These are starting prices. The exact cost depends on your app's features. You get the fixed price after the prototype.

These six questions determine your app's price.

The number of screens tells you little. What happens behind them drives the cost.

  • Which devices?A browser app, one codebase for iPhone and Android, or two separate apps. This makes the biggest difference.
  • Do users need an account?Registration, login, profiles and permissions for different roles cost more than an app anyone can simply open.
  • Where does the data come from?Connecting your app to your ERP, CRM or practice management software often takes the most work.
  • Will users pay in the app?Subscriptions, tickets or purchases need a payment provider, invoices and tests for every edge case.
  • Do you need an admin area?This lets you manage users, content and data yourself, without asking us for every change.
  • Do you already have a design?A finished UX/UI design saves you time. If you don't have one, we create it as part of the prototype.

We answer these exact questions during the prototype. Then we set the fixed price.

  • PetPlanner on two phones: appointments and booking a treatment

    PetPlanner

    Started as a prototype, now a German Stevie Award Gold 2026 winner

    Click first, build later: the prototype was the foundation for the app.

A calculator estimates. A fixed price stays fixed.

This page used to host our app cost calculator. But a number from six clicks tells us nothing about your data or systems, which is exactly where the costs come from.

ChatGPT can give you a price in a minute, too. But nobody will stand behind it. Drawing on our experience from over 200 projects, we work out the details of your app during prototyping, then give you a fixed price for the build.

This team plans your app and its price.

Charly builds your clickable prototype, Ivan and Strahinja design it, and Vera manages the project through to the fixed price.

This is for you if …

  • you need to approve a budget and want a reliable figure
  • your quotes vary widely and you don't know which to trust
  • you need something tangible to convince management, shareholders or investors
  • you want to see whether the app works before making a major investment

Common questions about app costs

How much does it cost to have an app built?

Our web apps start at €10,000, cross-platform apps for iOS and Android at €20,000, and native apps at €30,000. The exact price depends on the features, data and systems your app needs to connect to. After the prototype, you get a fixed price.

Why do you only give an exact price after the prototype?

Without defined features, data and integrations, the price would be a guess. That's what we work out in the prototype. If you already have a specification, let us know when you book and we'll bring a price range to the call.

What does an app cost after launch?

Servers and store accounts are in your name, and you pay the providers directly. If you want to keep growing your app, our design and development team is available from €2,699 a month.

Is a web app cheaper than an app in the stores?

Usually, yes. It doesn't need an app store, and one version works on all devices. An app needs to be in the stores if users should install it or it needs features such as the camera and Bluetooth.

Is the fixed price really fixed?

Yes. The price in the fixed-price plan applies to the scope we agree on together in that plan.

Who owns the code and design?

You do. The code, design and accounts are in your name, even if you later continue with another team.

What if the app won't pay off for me?

We'll tell you in the intro call, before you spend any money. With the prototype, you find out for €5,490 rather than €50,000.

How long does it take to finish the app?

You get the timeline along with the fixed price on day 21. It depends on the scope we define during the prototype.

We look at your plans with you as if they were our own. If building does not pay off, we tell you, even when that speaks against the project.
