“First-class collaboration with an exceptionally creative team”
We worked very intensively with Knguru in Q1 2026 on a concept for a new training platform in civil protection. The collaboration was excellent, and the Knguru team contributed a great many very good ideas of their own that went far beyond the scope of a UX design. I have never experienced such outstanding collaboration on a project with any other team, and I'm thrilled. I can recommend Knguru wholeheartedly and look forward to working together again.
From day one, working together was simply fun. Together we developed the design of an app for managing concert tickets, and our ideas and wishes were not only heard but actively taken up and developed further in a meaningful way. What we especially valued was that requirements weren't simply ticked off: whenever something wouldn't have been the best solution from a UX or product perspective, it was raised openly, honestly and always constructively – along with well-thought-out alternatives. The team really engaged with our project, contributed their own ideas and worked with us to create the best user experience for our customers. The feedback rounds were always constructive, the lines of communication short, and decisions could be made quickly. In the end, we not only got a modern, well-thought-out design for our ticket app that we are very happy with, but also a collaboration shaped by trust, transparency and real partnership. Everything ran reliably on schedule, and at all times we felt we were working on a solution together – not as client and service provider. That's exactly how you imagine working with an agency. ⭐️

“Professional collaboration as equals”
KNGURU developed the UI/UX design and the web app for us, and we are very happy with the result. The collaboration works excellently, both in regular online calls and in person on site. Together we discuss ideas, question processes and develop solutions that really fit the product in the end. We would especially like to highlight working with Vera and Louis. The chemistry is simply right – you can tell that they are not only strong professionally but truly understand our requirements and vision. Our own ideas are taken seriously, developed further together and implemented constructively. That creates the feeling of working on a product together rather than simply being client and service provider. Before KNGURU, we had worked with two other agencies and unfortunately did not have good experiences. That made us all the more pleasantly surprised by the transparent communication, the open collaboration and the fair pricing. You always know where you stand, there are no hidden surprises, and in our view the value for money is absolutely right. We look forward to continuing to work together and can recommend KNGURU to anyone looking for a reliable partner for modern UI/UX design and the development of high-quality applications.

“Top agency with a real feel for good design”
Working together is a real pleasure: you describe what you have in mind and get it back, only more beautiful and better thought through. Communication is fast and straightforward. On top of that comes a modern, well-thought-out design that not only looks good but also simply feels right to use. I have full confidence that Knguru always gets the best out of the requirements, and I look forward to the first drafts every time.

“Very happy with the collaboration”
We are working with KNGURU Studios on the launch of our new platform and are very happy with the collaboration. We especially appreciate how they think for themselves. The team doesn't simply implement our specifications but brings in its own ideas and develops them further in a meaningful way. You can also tell how much effort and attention to detail goes into the designs. Communication is fast and transparent, and we always know where the project stands. Feedback is taken up and implemented quickly. We are very happy with the collaboration so far and can recommend KNGURU Studios to anyone.

“Five years of strong and reliable collaboration”
Our collaboration with Knguru started around five years ago with the smartmove app and continues today, as the product is still developed. Knguru supports us with UX and UI design for new features and updates. They also designed and developed our new landing page, while the app itself was implemented by our team. What I appreciate most is that Knguru does more than simply turn requirements into designs. The team asks the right questions, challenges ideas when needed and often suggests improvements to the original concept. Their long term knowledge of the product and our goals makes discussing new topics much easier. Communication has always been straightforward and reliable. I can share feedback openly, decisions are explained clearly, and the team reacts well when priorities or requirements change. This has made the cooperation efficient and pleasant over the years. The quality of the work has remained consistently high. The designs are modern and polished, but usability comes first. This is especially important for smartmove, where users need a simple and intuitive way to book and use shared vehicles. The same approach was applied to the new landing page, which presents the product clearly. Considering the quality, experience and product knowledge Knguru brings to the project, I believe the value for money is fair. After five years, I see them as a dependable long term partner rather than simply an external design agency.
“His constructive feedback took our product to the next level.”
I worked with Louis on my project for about two months and I'm really very happy with him. I especially valued his open manner and his constructive feedback, based on his solid understanding of the market and of customers. I'd work with him again any time!
“Easy collaboration with excellent design results”
We have been working with KNGURU since the beginning of the year and are delighted all round. Coordination is easy and fast, the team responds quickly to requests, is friendly throughout and always implements feedback promptly and carefully. We especially value their proactive thinking: KNGURU brings in its own creative suggestions but also implements stricter requirements consistently and reliably when needed. The design itself is lovingly thought through and always user-centered – which also goes down extremely well with our stakeholders, who are thrilled with the results. The designs of our portal have even become the model for our client's new digital style guide.
- Very likeable and competent team
- Very modern, high-quality designs, not only beautiful but also easy to use
- Communication was fast, straightforward and always on equal footing
- You can tell that KNGURU has a lot of experience with apps, websites and digital products
- Clear processes and transparent collaboration
- Highly recommended for UX/UI, web design and app development in Leipzig
“Professional collaboration with transparent communication”
Our new website is still being built, but so far we are very happy working with KNGURU. The team works professionally, understands our ideas and implements them very well. We especially appreciate the fast communication and the transparent way of working, which lets us follow the project's progress at any time.

By day 21 you hold a prototype, a recommendation and a fixed price.
01
Clickable prototype of the 3–5 key features
Testable on any phone. Realistic enough that users give real feedback.
02
Core screens for management, investors and first user tests
Design language and core screens for management, partners or investors, before any code is written.
03
Two strategy calls
A kickoff call to refine the scope, then a debrief to decide what comes first and what to leave out.
04
Fixed-price plan for the build
Features, phases and a binding price, plus what data protection and your systems require.
By day 21 you have answers: What gets built, and what deliberately doesn't? What does the first useful version cost? Which risks are still open, such as data protection or integrations? And what will win over management, IT or investors?
Interim review on day 10, fixed price on day 21.
Day 1
Kickoff call
Days 2–17
Prototype and design, interim review on day 10
Days 18–20
Polish and fixed-price plan
Day 21
Debrief call: prototype, recommendation, price
Fixed price
€5,490
If you build with us afterwards, we credit the full €5,490. Prototype, design and plan are yours.
Our promiseWhat we agree on at kickoff is clickable on day 21. If not, we keep working for free until it is.
To keep to the 21 days, we start no more than six sprints a month.
Launched as a prototype in 2025, now 60,000 registered users
In 2025 DeepDays ran as a prototype, already with real users in the App Store. The full version went live in early 2026: over €1 million in ticket sales through the app in its first year, 4.8 ★ on the App Store and Google Play.
Glücksgefühle Festival
The prototype for a festival with 200,000 visitors
A clickable prototype, built quickly so the team could try out the app before development.
PetPlanner
Started as a prototype, now winner of the German Stevie Award Gold 2026
Click first, then build: the prototype was the basis for the app.
ChatGPT can create screens in an hour. It can't give you a fixed price for development.
ChatGPT and other AI tools get you screens fast. What's missing is the decision: what scope makes sense, which features users really need and what roles, data and integrations will cost later.
You make that decision with us, backed by experience from over 200 projects. We use existing clickable mockups as a starting point. Your IT team brings its knowledge of your systems, but doesn't have to carry the project on top of its day-to-day work.
This team builds your prototype.
Charly builds your clickable prototype, Ivan and Strahinja design it, and Vera runs the project through day 21.

Development, design and marketing
This is for you if …
you want to see if the app works before you invest big
you need to win over management, shareholders or investors with something tangible
you need a clear decision within three weeks
you want to turn an internal tool into a product for customers
We'll recommend something else if …
your AI prototype is already running and should get real users soon. Then we'll help you turn it into a real product.
That's in the fixed-price plan you get on day 21. We credit the full €5,490. You don't have to keep building with us.
Is the prototype already the app?
No. It's clickable and feels real, but there's no code running behind it yet. It shows whether your features work the way you imagine them, and it's the blueprint for the build.
Who owns the prototype and design?
You do. All files, screens and the plan are yours, even if you don't keep building with us.
What if the idea doesn't hold up?
Then you find out for €5,490 instead of €50,000. That's a result too, and we'll tell you openly.
How much of my time is needed?
Two calls and feedback on the interim review on day 10, usually within two days.
Do you also build a waitlist page?
Yes, if you want one, so you can test real demand. We'll sort that out at kickoff.
What about data protection and our systems?
We work out both in the sprint: which data the app needs, where it's stored and which systems it has to connect to, such as an ERP or practice management software. It's in the fixed-price plan before a single line of code is written. Not every risk is solved after 21 days, but none stays hidden until the build starts.
We already have a spec. Do we need the sprint?
Not necessarily. Mention it when you book, and we'll bring a price range for the build to the call.
Book your free call.
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.
