Mobile App Development Services
Your Mobile Product.
The Right Approach.
Build and improve iOS and Android apps with a senior delivery team. We bring product design, React Native, Swift and Kotlin together around your users, existing systems and roadmap.

Mobile product delivery
From First Release
to What Comes Next.
Turn a customer journey or an operational workflow into a mobile product people can use. We help define the first useful release, design its interactions and connect it to the systems your business relies on.
Already have an app? We can work with your team on new features, integrations, reliability or a staged modernization. We start by understanding the current product and the constraints behind the next release.
What we deliver
One Product.
Clear Responsibilities.
Agree the scope, deliverables and ownership of each stage before implementation.
Product & UX
Define the audience, core journey and acceptance criteria. Prototype uncertain interactions and account for loading, offline, error and permission states.
Apps & Integrations
Implement the agreed iOS and Android experience, APIs and device integrations. Coordinate with your backend team or include backend delivery in the scope.
Release & Maintenance
Test the critical journeys on agreed devices. Prepare store submissions, monitoring and handover, then plan support and platform updates.
Native or cross-platform
Choose for the Product.
Then Build with Focus.
Swift for iOS and Kotlin for Android suit products where platform-specific interfaces, device capabilities or independent platform roadmaps are central. Each platform still needs its own verification and release work.
React Native is worth evaluating when the two platforms share a core experience and common implementation helps the team. Native integrations and platform-specific behavior remain part of the delivery plan.
We compare those options against your requirements and an existing codebase where relevant. You can also launch on one platform first when that is the clearest way to test demand.

React Native demo applications
See the Interactions.
Discuss Your Product.
Explore Makers’ Den’s React Native demonstration apps, covering commerce, marketplace and shared application flows.
Sneakers App
A commerce demo with shopping, product drops and editorial content. Explore how those journeys work together in a mobile interface.
APRMTS Rental App
A rental marketplace demo with registration, sign-in, listings, search and map navigation.
Universal App
Our estimation app explores sharing an implementation across web, iOS and Android.

Delivery and ownership
Plan the Launch.
Own the Next Release.
We show working software throughout delivery and use agreed acceptance criteria to keep scope decisions visible. Device testing, accessibility, network failures and integration behavior belong in the plan from the start.
Before launch, establish company access to repositories, store accounts and infrastructure. Agree who handles incidents, dependency and operating-system updates, release decisions and the next product iteration.
Store preparation and submission support can be included in the engagement. Approval dates remain outside the delivery team’s control, so we keep them separate from the implementation forecast.
For existing products
Improve What Works.
Test What Should Change.
A new framework is not a reason to replace a working app. Identify the constraint first: user experience, delivery speed, platform integration, stability or maintainability.
If the architecture decision is blocking progress, our Mobile Architecture Assessment examines the product, codebase and delivery setup and recommends a practical next step. It can lead to targeted improvements, a mixed approach or a staged migration.

Mobile App Development FAQs
Questions Before
You Start Building.
Do you build native iOS and Android apps as well as React Native apps?
Yes. Our mobile offer covers Swift for iOS, Kotlin for Android and React Native. We agree the platform approach around the product experience, integrations, existing code and the team that will maintain it.
Can you improve an existing mobile app?
Yes. We can work on features, integrations, performance or reliability within an existing app. We review the relevant code and release process before recommending the scope; a rewrite is not the default.
How much does mobile app development cost?
The estimate depends on the first release, platform coverage, design readiness, backend and device integrations, testing requirements and team availability. We define assumptions and exclusions, then provide an estimate for an agreed scope.
Can we launch on one platform first?
Yes. A first release can focus on iOS or Android if that reaches the intended users and tests the right assumptions. We make the implications for the second platform explicit when choosing the architecture.
Do you help with app-store releases and ongoing maintenance?
We can include store preparation, submission support, monitoring, handover and maintenance in the engagement. Store approval is controlled by Apple and Google. Support coverage and update responsibilities are agreed as part of the scope.
What should we bring to the first conversation?
Bring the user journey, business goal, target platforms, existing app or systems, and any budget or timing constraints. For an existing app, a product walkthrough and the main delivery problem are a useful starting point.
I want to keep my idea confidential. Will you sign an NDA with me?
Yes, we sign an NDA (Non-Disclosure Agreement) always when a client wants it. We can do it at the very beginning before we discuss your project's details, or at another stage of the process - it's up to you.
Do I own the intellectual property rights of my application?
Yes, you are the owner of Intellectual Property rights at all times.
Where is your development team located?
We are fully remote. So while we were founded and are still based in Berlin, most developers will be remote from a central European location.
What is the pricing model?
You work with us on a Time & Materials basis. The total cost depends on the actual time the team spends on the development. You are in charge of the project’s scope and set priorities for the development team.
Time & Materials allows flexibility for you to set the direction of development depending on the users’ feedback, market situation, or opportunities that arise during the development.
For more about how we create estimates read how to estimate software projects .
What would my development team look like?
We adjust the team depending on your needs. Our speciality is low overhead teams, where every member is contributing concretely towards customer facing features. That means everyone is either doing development or design.
Roles like Project Manager, Business Analyst and QA are responsibilities which are shouldered by our business oriented developers or designers.
You may take the role of a Product Owner, making decisions on priority and scope.
Can you work as an amendment to our in-house team?
Yes. We can adapt to your tools and processes. I.e. fully integrate into your existing team.
How does the company ensure code quality and maintainability?
We follow best practices, perform code reviews, implement automated testing and continuous integration to ensure code quality and maintainability. All projects are not equal though and the level of automated QA will be determined on your need for quick feedback from the market.
Can you hand the code over to another team?
Yes. We create easily understandable and maintainable code using well known frameworks which don’t require niche knowledge.
The runtime environments we can set up in your ownership from the get-go.
What is the experience level of my team?
Every team has a partner involved in the project. Our developers have a proven track record of outsized throughput. Our culture is one of delivering features every day. That's why we prefer senior developers, but not seniors that are from slow moving enterprise environments.
How am I kept up-to-date of development?
We have fixed length iterations (usually 1 week), at the end of which you will be demoed the current progress. You will have access to team members through Slack, email and video calls and our regular meetings. In addition to this you will have access to our project management tools (Jira or Asana), which we update daily.
Why hire us?
We love what we do and only employ people with a similar mindset. You ship faster by working with a small team where each developer is a focused on your business goals. With us you get direct access to everyone. This keeps overhead low and output high.
You are in control. We offer full transparency of progress and potential problems. We keep you informed and present options, but you make the decisions.
We value our client relationships and their product visions. Meet with us to see if we share the same conviction. We might be a good fit.
