Your app is live. But no one is finding it.
We bring apps out of obscurity with app store optimization, paid ads and the UX know-how most marketing agencies lack. That's how we took our own app, DeepDays, to 60,000 users.
Recognized for design, user experience and digital innovation
Nine out of twelve reviews say the same thing: we push back when something won't work for users.
“The new design gave our conversion a 31% uplift.”
I always thought it would be about the code, but our users care much more about the design! It was more than worth it.

“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.

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.
How we grew DeepDays to 60,000 users
DeepDays is our own app for car events. In January 2026 it had zero users, today it has 60,000, and every euro spent on ads was our own.
01
Positioning
Every car meet in one app. One clear reason to download it.
02
UX/UI
Event pages that sell. Tickets go straight into the wallet.
03
Measured marketing
Ads per event in the local area, tracked all the way to the ticket sale.
App marketing: full service from design to marketing
Project check
We talk about your app, where it stands and what actually makes sense. Free and with no strings attached.
Product analysis
We take a close look at your app and find where the UX and UI are holding it back. Sometimes a small fix is enough, sometimes it takes more.
Marketing strategy & execution
We set target numbers with you, set up tracking and produce the first creatives. Strategy and execution come from one team.
Run and improve the campaign
We actively manage every campaign and keep a constant eye on its numbers. What the numbers show goes straight back into the campaign.
Having an app in the store doesn't mean you have an app on the market.
We run paid campaigns, improve your store presence and make sure the users you win actually stay.
01
Paid user acquisition
Apple Search Ads, Google and social media, managed for return on ad spend rather than reach. Audience analysis and clean tracking are part of it.
02
Creative production
Mockups, videos and ads made for downloads, not just to look nice. Plus store assets like icons, screenshots and preview videos.
03
Retention & lifecycle marketing
Winning new users costs money, keeping them earns it back. We improve onboarding, push notifications, in-app messages and emails so fewer users drop off.
04
Performance monitoring
Without numbers, every marketing decision is a guess. We track rankings, installs, cost per install, retention and active users, and report back to you regularly.
05
Launch strategies
For anyone about to enter the market or release the next version of their app. We plan the timing, soft or big launch, pre-launch page, PR and beta testing.
06
App store optimization
Many installs start with a search in the store. We improve keywords, title and description for each market so more visitors to your store page install.

Development, design and marketing
Are you looking for professional app marketing?
Wondering if we're the right partner for your project? Get in touch and we'll talk about what makes sense for your app.
Who is your service best suited for? Does my app need to be a certain size?
There's no fixed threshold for downloads or revenue, but your app has to keep its users. If most of them are gone after day one, that's a product problem, not a marketing problem, and we'll tell you so in the audit. Our work fits best for B2C apps with subscriptions or in-app purchases, marketplaces, and community or event apps.
My app isn't in the store yet. Can I still work with you?
Yes. Our focus is on apps that are already live, but we also handle launches: keywords, name, screenshots, preview video, tracking and, depending on the project, a soft launch in a smaller market. If you bring us in early, your store presence and onboarding are built alongside the product instead of three months later as a stopgap.
I already have an agency for ASO or ads. Can I book individual services from you as well?
Yes, our services can be booked individually, for example just the creatives or just ASO. Beforehand, we agree on who decides what. Two parties tweaking the same campaigns at the same time is the surest way to get bad data.
How does the collaboration actually work? Do I get a fixed point of contact or rotating teams?
You get one dedicated contact who supports your project from kick-off through to ongoing operations. Our whole team is employed in-house, from design and development to marketing. Nobody has to get up to speed on your product all over again every few months.
How quickly can a campaign start once we've decided to work together?
Realistically in two to four weeks, while we analyze keywords and competitors, set up tracking and produce the first creatives. The bottleneck is almost never our team but the tracking in your app, because the SDK and events take time from your developers. If that's already in place, we can be live in one to two weeks.
How soon can I expect results?
ASO usually shows an effect after two to four weeks, because the stores first index and test changes. Paid campaigns deliver data right away, but the first two weeks are a learning phase. Reliable numbers on cost per install and retention come after four to six weeks, and real optimization kicks in from month two or three.
Can you guarantee a certain number of downloads or a specific ROAS?
No, and anyone who does should make you suspicious. Installs and ROAS also depend on your pricing, your store page, first-week retention and the competition. What we do commit to: a forecast based on comparable projects, target numbers we agree on before launch, and full transparency on every euro spent.
What happens if a campaign doesn't perform as expected?
We work with fixed cut-off rules: weak creatives go early, campaigns that cost too much get rebuilt, and we stop a channel with no positive trend after about four weeks. If no channel works after six to eight weeks, the problem is usually the product, such as retention, onboarding or monetization. Then we tell you, recommend pausing the ads and help right away, because design and development are in-house.
Do you also produce the creatives, or do I need to supply them myself?
We make the creatives ourselves, since design is in-house. Without your own production, you often wait two weeks for a new video variant, and that kind of lag is where many campaigns fail. All we need from you is your logo, fonts and colors.
Do you cover other countries and languages, or just the German-speaking market?
Our focus is the German-speaking market, where we know the channels, costs and competition best. We also run international campaigns and translated store pages. We'll tell you upfront where we have our own experience and where we'd be starting from scratch.
What's the difference between ASO and paid user acquisition? Do I really need both?
ASO makes sure your app gets found and that visitors to your store page install it, while paid ads bring enough visitors there in the first place. A weak store page makes every paid click more expensive, which is why we start with ASO before any ad budget goes out. In competitive markets, ASO alone is often too slow, so using both is the norm, just in that order.
What does your monthly service cost?
We bill marketing the same way as our design work: a monthly contract with a fixed bank of hours. You know upfront what you'll pay and can see where the hours go.
Is there a minimum contract term, or can I cancel monthly?
You can cancel monthly, like all our packages. Paid user acquisition rarely makes sense for less than three months, though, because the algorithms spend the first two weeks learning before real optimization starts. Pure ASO work can also be booked as a standalone project without an ongoing contract.
What budget do I need before paid user acquisition makes sense?
That depends on the channel and your goal, and we'll work out in a call whether ads pay off for you. Apple Search Ads works with a small budget, and ASO needs no ad budget at all. If your budget is tight, that's exactly where we start.
Do I pay anything for the initial audit, even if I don't end up working with you?
No, the audit is free and comes with no obligation. We look at your store listing, keywords, competition and any past campaigns and tell you where you stand. Sometimes the result is that we advise against it, and we'll tell you that just as plainly.
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.
