Custom mobile app development company | iOS & Android developers

Both app stores. One budget.

We build apps that work on iOS and Android from one codebase. You reach all your users without doubling your investment.

Custom mobile apps and software we build

Let’s figure out what problem you’re actually solving.

Business Tools

Internal apps for teams: employee directories, vacation requests, company news, quick access to resources. These applications streamline operations and keep distributed teams connected without relying on clunky intranets or email chains.

Content & Media

Streaming apps, content platforms, niche media services for specific audiences. Whether you're delivering video, audio, articles, or interactive content, mobile applications provide the engagement and retention that web browsers can't match.

E-Commerce & Transactions

Mobile shopping, payment processing, order management, loyalty programs. Ecommerce apps convert better than mobile websites and build customer habits through convenience, saved preferences, and push notification reminders.

Utilities & Automation

Task automation, data collection, field service tools, offline-capable workflows. When your team works in the field or needs to capture data without reliable internet, mobile apps solve problems that websites simply can't.

What you’re actually building:

The app on your phone is only 30-40% of the work. The rest is infrastructure: databases, APIs, authentication, notifications, and server management. We handle all of it. Learn more about the backend and API work that powers mobile apps.

Full-service mobile app development

Whether you need a simple utility or a complex enterprise solution, our app development services cover the full lifecycle. We handle everything from initial concept and app design through development, testing, and app store submission.

Our developers work with you as a partner, not just a vendor. Every mobile application development project starts with discovery — we ask questions, listen carefully, and make sure we understand what you actually need before writing a single line of code.

As a full-service mobile app development company, we offer custom and bespoke software solutions tailored to your business. That includes cross-platform mobile applications, iOS Android development from a single codebase, native app development, API integrations, and ongoing support after launch.

If you’re comparing app development companies and agencies, here’s what sets us apart: we don’t just build software. Our mobile app development services are designed around your situation, backed by a development team that stays with your project from discovery through launch and beyond.

When you need a mobile app development agency

Mobile apps make sense when you need app-specific capabilities. If a responsive website solves your problem, you probably don’t need an app.

Your situation
Mobile app?
Users interact with your service daily or weekly
Yes
You need to send push notifications
Yes
Offline functionality is required
Yes
Using device features (camera, GPS, sensors)
Yes
Large or growing user base
Yes
Automating repetitive tasks for users
Yes
Users interact infrequently (monthly or less)
Maybe not
Small user base (under 200 users)
Maybe not
No app-specific features needed
Maybe not
A responsive website solves the problem
Probably skip

Not sure?

We’ll help you figure out whether a mobile app, web app, or website makes the most sense. Start with discovery to get clarity before committing.

Why cross-platform?

The traditional native approach means building two separate apps: one for iOS, one for Android. That’s two codebases, two timelines, and roughly double the cost.

We use cross-platform app development instead. One codebase produces native-quality applications for both platforms. Same functionality. Same quality. Significantly lower investment. Whether you’re weighing native development against multi-platform solutions or considering hybrid apps, the math favors a single-codebase approach for most projects.

Native Development

Traditional
(01)
Two separate codebases to build and maintain.
(02)
Two development teams or doubled timeline.
(03)
Updates deployed separately.
(04)
Double the testing across platforms.
(05)
2x the cost for the same functionality.

Cross-Platform

Our Approach
(01)
One codebase serves both iOS and Android.
(02)
One team, one process, simultaneous deployment.
(03)
Updates roll out to both platforms at once.
(04)
Unified testing with platform-specific checks.
(05)
25-40% cost savings, 30-50% faster delivery.

How our mobile app development services work

Mobile app development follows a structured process. Each step builds on the previous one.

Our mobile app developers

Every project is handled by experienced app developers who’ve shipped real products to real users. Our developers specialize in React Native cross-platform development, and they’ll guide you through every decision from architecture to app store submission.

Your dedicated developer and development team

You won’t be handed off to junior developers or outsourced contractors. Your development team stays consistent from kickoff to launch. That means fewer miscommunications, faster decisions, and a developer who actually knows your project inside and out.

Pricing

We’re not the cheapest. Here’s why that’s good news.

A 20-30% investment in quality app development pays for itself through lower maintenance costs, fewer critical bugs, and better user retention. The cheapest bid often becomes the most expensive project. Mobile app development pricing depends on complexity, features, and requirements. Here’s what to expect.

Frequently asked questions

Common questions about mobile app development, our process, and what to expect.

Cross-platform (React Native) saves you 25-40% on cost and 30-50% on time compared to separate native apps for iOS and Android. You get one codebase that produces native-quality apps for both platforms, with easier maintenance and faster updates. We’d only recommend native if your app requires specific device APIs that React Native doesn’t support, which is rare.

App development takes 1 month to 1 year depending on complexity. Simple apps with basic functionality: 1-3 months. Complex applications with user authentication, payment processing, real-time data, and third-party integrations: 6-12 months. Our developers will give you a realistic timeline after discovery.

Yes. If you have the resources and knowledge to handle registration and submission yourself, you can. If not, we’ll handle the entire process for both Apple App Store and Google Play Store, including future updates. App store reviews can take days to weeks, and rejections happen. We’ll guide you through it.

Every app comes with a 6-month warranty covering bugs and errors discovered after launch. If something breaks or doesn’t work as intended, we fix it at no extra cost. The warranty doesn’t cover new features, design changes, or issues caused by third-party services. Just bugs in the code we delivered.

Yes. Mobile apps require regular updates. iOS and Android release new versions constantly, policies change, and APIs get deprecated. Your app needs maintenance to stay compatible and compliant. We offer Support & Maintenance packages starting at €50/month, or 3 months free if we built your app.

We build cross-platform, which means you get both iOS and Android from one codebase. App development for just one platform doesn’t save much cost. You’re still paying for the same development process and infrastructure. We recommend launching on both to maximize reach and ROI.

Because cheap apps cost more in the end. A 20-30% investment in quality development pays for itself through lower maintenance costs, fewer critical bugs, and better user retention. We build apps that work well and stay working, not apps you’ll need to rebuild in two years. The cheapest bid rarely wins in the long run.
