Custom Mobile App Development – from Concept to App Store
Do you want to develop a custom mobile app that simplifies your processes and that your customers actually use? We build iOS and Android apps with Flutter or React Native – from conception to launch.
What does it mean to develop a custom app?
Developing a custom app means turning an idea or an existing process into a mobile application – for iOS, Android, or both.
We handle conception, development, testing, and release in the Apple App Store and on Google Play. Apps are part of custom software development: They solve a specific business task and connect to existing systems. Looking for an app agency that delivers concept and development from one team? You're in the right place.
Which apps we build for companies Three typical starting points – one goal: a workflow that works on mobile.
Customers
Customer apps
Apps for orders, bookings, loyalty, or services – with login, push notifications, and integration with your CRM or ERP.
Team
Employee apps
Mobile applications for field service, time tracking, documentation, or communication – usable offline, too.
Processes
Process apps
Apps that digitize a manual workflow: scan, review, approve, synchronize – connected to your systems.
Who benefits from an app – and when it's not the right fit
An app pays off when a workflow regularly happens on a smartphone or tablet and an off-the-shelf product doesn't cover it. That applies to customer apps with login and push as well as employee apps in field service or production.
An app is less useful when a mobile website already serves the purpose or an off-the-shelf industry product covers the process. In the intro call, we'll tell you openly which option fits your project.
- Fits: Your team or your customers work with the workflow every day.
- Fits: You need camera, GPS, Bluetooth, push, or offline access.
- Fits: The app needs to connect to CRM, ERP, or other systems.
- Less useful: A mobile website is enough for content and simple forms.
App or mobile website? What fits your project The decision depends on what your users need to do – not on the technology.
An app pays off when you need push notifications, offline access, or device features. A mobile website or PWA is enough when content and simple forms in the browser do the job. We build mobile websites/PWAs and cross-platform apps; native development is reviewed case by case. The table helps you choose.

How app development works at northcommit From the first idea to operation – in clear phases.
Step 1 of 6: Intro call
Intro call
In the free intro call, we clarify what the app should do, who will use it, and which systems need to be connected. You get an initial assessment of effort, risks, and a sensible first version.
Outcome: a shared understanding of the goal, scope, and next step.
Conception
We define features, user roles, and the technical architecture. Instead of building everything at once, we scope a first version that delivers the core value.
Outcome: a prioritized feature set and a reliable roadmap.
UX/UI-Design
Wir gestalten Wireframes und einen klickbaren Prototyp. Nutzerführung und zentrale Abläufe werden getestet, bevor die Entwicklung beginnt.
Ergebnis: ein Design, das deine Nutzer verstehen – und das deine Marke trägt.
Development
We develop in short sprints and regularly deliver testable versions. You see progress, give feedback, and can adjust priorities.
Outcome: a working app that gets closer to the goal with every sprint.
Test & launch
We test on real devices, check security and performance, and support the release in the Apple App Store and on Google Play.
Outcome: an app that passes store review and is ready to launch.
Operations & further development
After launch, we take care of updates, bug fixes, and new features. You decide whether we run operations or hand them over to your team.
Outcome: an app that stays maintainable and grows with your business.

Flutter, React Native, or native app?
We choose the technology based on your goal, not the trend. Flutter and React Native cover iOS and Android with one codebase. For projects with special requirements, we discuss in the intro call whether native development makes sense and how we can cover it.
- Flutter: one codebase for iOS and Android with a consistent UI.
- React Native: one codebase for iOS and Android, close to the React ecosystem.
- Native development: an option for maximum platform performance and special device requirements – reviewed in the intro call.
- Backend and integrations: APIs, databases, CRM/ERP, and cloud operations.
How much does it cost to develop a custom app?
Costs depend on the feature scope, platforms, and required integrations. An app with login and one core feature is built much faster than a solution with multiple roles, offline synchronization, and ERP or CRM integration.
That's why we don't quote a flat fee. We estimate the effort after the intro call and decide together which features belong in the first version. In the free intro call we clarify which option fits your budget.
- Feature scope and user roles
- Number of platforms
- Design and user experience
- Integrations, backend, and operations

FAQ Frequently asked questions
What it costs to develop a custom app depends on the feature scope, platforms, and integrations. We estimate the effort in the free intro call and scope a first version that delivers the most value. We deliberately don't quote flat fees.
App development time depends on scope: a first version with a few core features is testable sooner than an app with multiple roles and system integrations. After the intro call, you get a plan with phases and milestones.
An app is the better choice when you need push notifications, offline access, or device features such as camera and GPS. A mobile website or PWA is enough when content should be accessible without an app store. We compare both options in the intro call.
Yes, we develop apps for iOS and Android. For most projects we use Flutter or React Native with a shared codebase. If a project requires native development, we discuss in the intro call whether and how we can cover it.
northcommit is a software development partner with an in-house team in Germany. You get conception, development, and operations from one source – with a dedicated contact throughout the project. In the intro call, you meet the team that will later work on your app.
After launch, we handle updates, bug fixes, and new features on request. Alternatively, we hand operations over to your team and document the transition. That keeps your app maintainable after release.
