Over 90% of apps don't fail due to development – but because users ultimately aren't willing to pay for them. This is precisely what sets KNGURU apart from other developers.
How much does your app cost?
The more features your app is intended to have, the higher the development costs typically are. Therefore, we recommend starting with the leanest and most clearly defined version possible and then expanding the app strategically later. This way, costs can be reduced, initial results achieved faster, and user feedback incorporated into further development early on.

Those who cut corners in development risk their profits
We combine the flexibility of freelancers, the reliability of in-house designers, and the structure of an agency – without the usual compromises.
An appealing design is a prerequisite for the success of any app and also reduces development costs.


For customers to trust your app and spend money on it, it must function flawlessly from a technical perspective.
We ensure your software runs smoothly and efficiently by minimizing downtime.

Before we develop, we plan your app in detail. In UX/UI design, we define how everything works – ensuring programming isn't just done haphazardly later on.
Prototype, not gut feeling
You can test your app before it's developed. This way, we see early on what works – and avoid costly mistakes in app development.
App Development & Launch
Now we implement everything – structured, transparent, and without chaos. With a clear plan, fixed processes, and an app that works exactly as intended.
How much does each individual feature cost?
Naturally, the more features your app needs to include, the more expensive it will be. Therefore, we always recommend developing the app as compactly as possible initially and expanding it later.
A real-time live feed for your app, where users can discover new content, interactions, and activities from their community.
Integrate event features into your app, allowing users to create, discover, and manage their participation directly.

Send automatic push notifications directly to your users' smartphones and keep them engaged in your app with updates, reminders, or new content.
Create, discover, and respond to events directly within the app.
Enhance your app with a map feature that allows users to easily share live locations and fixed places.
Enhance your app with powerful search and filter functions to make content, places, or users easily discoverable.

Frequently Asked Questions about UX UI

What does a UX UI design agency do?
A UX UI design agency plans and designs digital products so that users understand them, enjoy using them, and quickly achieve their goals. This includes user flows, wireframes, interface design, prototypes, and preparation for development.
How much does UX UI design for an app or website cost?
The costs depend on the scope, complexity, and number of screens. Our UX UI workshop starts at 1,499 Euros. For ongoing design work, we offer predictable monthly packages.
When is a UX UI redesign worthwhile?
A UX UI redesign is worthwhile if users are dropping off, processes are too complicated, or your product no longer looks modern. Often, a targeted optimization of existing user flows is enough, instead of building everything from scratch.
Why should UX UI design happen before development?
Good UX UI design prevents costly development errors. If the structure, user guidance, and interface are clear beforehand, development can proceed faster, cleaner, and with less rework later on.
Can you also handle just UX UI design?
Yes. We handle complete product concepts, individual UX UI designs, or redesigns of existing apps and websites. The finished design can then be implemented by us or by your own development team.
How does a UX UI project with you work?
We start with a free initial consultation. This is usually followed by a workshop where we clarify the target audience, features, and user flow. Afterwards, we design wireframes, the interface, and a clickable prototype in Figma.
