SaschaGoogle reviewTranslated from German“Top service, top results”
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. ⭐️

SophiaMarketing Manager, München Ticket GmbHTranslated from German“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.

SteveManaging Director, nextGYM GmbHTranslated from German“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.

MichaelCTO, smartmove“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.

GraceGoogle reviewTranslated from German“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.

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.

iOS App Development for the Apple App Store
Proper Preparation Prevents Poor Performance! Our well-established development process sets the right course for your success from the very beginning.
01
UX/UI Design – First Impressions Matter
Today’s users expect thoughtful and visually appealing design—your app needs to compete visually with platforms like Google, Facebook & Co., and it should be intuitive and enjoyable to use. That’s exactly what our professional UX/UI designers deliver.
02
MVP Development – Build, Measure, Learn
Once the visual mockups are complete, our developers build the first usable prototype—the so-called Minimum Viable Product (MVP). This allows us to test the core idea behind the app together and address any fundamental issues before the codebase grows too large.
03
Development in Sprints – Agile Development for Fast Results
Once the MVP has proven itself, we plan the further development together and set intermediate goals—such as key features. We implement these following the SCRUM model in sprints that each last a few weeks.
04
Publishing in the App Store, Updates and Support
Once the project is ready for market, we can publish the app in the App Store. We have the required Apple Developer account and ensure throughout the development process that Apple’s guidelines are followed so your app passes the review process smoothly.
iOS App Development at Knguru - That’s Why We Use React Native Instead of XCode and Swift
The same codebase takes your app to Android too: this is how it works for an Android app. When a native app is worth it has its own page, and everything else is under app development.
01
Swift and XCode – Development Environment and Programming Language for iOS
Apple provides its “official” tools for creating iOS apps for iPhone and iPad: the Swift programming language (or Swift alongside Objective-C) and the XCode development environment integrated into the Apple Developer Program. Developers who want to build apps specifically optimized for Apple devices typically rely on these tools.
02
iOS App in the Apple App Store – Even with React Native
You can confidently skip Swift when developing for iOS. iOS app development is entirely possible without Swift or XCode—by using a framework that supports all major platforms from the ground up. This approach is called cross-platform app development.
03
Have Your Own App Built – Our Developers Bring the Code to Every Device
We pay close attention to all the critical details when developing mobile applications. Before development begins, we assess the app’s performance requirements and necessary permissions, and we take into account the different style guidelines across platforms.
Built for clients. In use today.
A Gold Stevie Award, 200,000 festival visitors, 4.4 stars on Google Play. Eight of over 200 projects, all live, every screen real. Two more we can name but not show.

The platform for pet owners and pet professionals
With PetPlanner, pet owners find the right service providers near them, book appointments online and keep track of their pet's health data, appointments and key information at any time.
Energy that adapts to your life.
Clever-PV wanted more than just an app. They wanted to give households control over their energy. Our job: a UX and UI design that makes data clear, intuitive and easy to understand.
The app for everyone who loves cars and motorsport!
DeepDays is the app for car events, community voting and digital ticketing. From the first idea through UX/UI design to the technical build, we developed the product entirely ourselves and scaled it to over 50,000 users in a short time.- 200,000visitors

A festival that lets you play along.
For the Glücksgefühle Festival we built an app that gives 200,000 visitors interactive experiences, from ticketing and gamification to live communication. 

Cook together with your favorite creators
Scoops connects food creators with their community in a new way. Influencers share their recipes right in the app, and their followers unlock them with a subscription, cook along and become part of an active food community.
Manage thousands of vehicles at a glance
Smartmove needed a way to manage its vehicle pool efficiently. We built an intuitive interface with smart automation that's easy to understand in 10 seconds.
Recruiting software on autopilot
Recruiting is often chaotic and manual. With Funellab we built a platform that filters, organizes and matches applicants automatically.
Complex CAD workflows made simple and intuitive.
Mensch und Maschine specializes in CAD and BIM software. We built an intuitive solution that simplifies complex processes and makes it easy for teams to work together.- Confidential

For Red Bull Salzburg. That's all we can say.
Not every project can be shown. What we worked on for Red Bull Salzburg stays confidential. If you build with us, you can count on the same discretion. - Confidential

For Evergreen. And that stays between us.
What we did for Evergreen stays in-house. Here too, we can't show anything. If you build with us, you can count on the same discretion.
Let’s have a chat!
Still not sure if we’re the right fit to help you out? Just book a free consultation with us or take a look at our FAQ section.
Does iOS development with cross-platform frameworks offer the same capabilities as a “real” iOS app?
In almost all cases, yes. There are still some differences in performance or access to certain device features in specific areas. However, it’s quite likely that Apple will gradually remove these limitations as cross-platform apps become more popular.
Aren’t universally usable apps more expensive than native iOS apps?
Nope! Building apps with cross-platform frameworks is often even easier. In many areas, they are more developer-friendly than the tools Apple provides for mobile app development.
I heard Swift Playgrounds is still around. Doesn’t that make app development faster?
Not at all! This tool is purely a learning platform. It’s not really intended for professional app development.
Book your free call.
We look at your plans with you as if they were our own. If the build isn't worth it, we'll tell you, even if that means no project.
