App Development

Apps that people actually use — not just download.

We build cross-platform and native apps from concept to App Store. Strategy, design, development — one team.

  • From idea to a working app on iOS and Android.
  • One codebase, two platforms — faster to market with Flutter.
  • Transparent packages, proven process, store-ready results.

1Team — concept to store

Three reasons companies come to us for apps.

MVP · New ProductValidating a new idea

You need a working app that proves the concept — not a prototype that falls apart in the demo. We build MVPs that ship to real users.

Business App · DigitisationReplacing a manual process

Your team still works with spreadsheets, paper or outdated tools. We build the app that makes the process faster, more reliable and mobile.

Scale · RebuildThe current app can't keep up

Your app is slow, hard to maintain or stuck on an old stack. We rebuild on a modern foundation — so it scales with your business.

What you get

Not a prototype that needs rebuilding. We deliver production-ready apps — designed, developed, tested and submitted to the stores.

Cross-platform or native app

iOS and Android from one codebase (Flutter) or native development where it matters. Your choice, our recommendation.

UX/UI design

User flows, wireframes and a complete UI — designed for mobile, tested before development starts.

Backend and API integrations

Authentication, data storage, third-party APIs — the backend your app needs to work reliably.

Store submission

We handle App Store and Play Store submission including screenshots, descriptions and review compliance.

Post-launch support

Bug fixes, OS updates, performance monitoring. We stay with the project after launch — not just until handoff. Retainer option available for ongoing maintenance.

How we work

No guessing, no scope creep, no surprises. Our process is structured and transparent — from the first conversation to store submission.

01
Strategy Call

30-45 minutes, free, no pitch. We listen, understand your idea and tell you honestly what it takes to build it.

02
Proposal & Kickoff

Fixed scope, fixed price, clear timeline. In the kickoff we define features, user stories and technical architecture.

03
Design

User flows, wireframes, UI design. You see and test the app before we write a single line of code.

04
Development & Testing

Sprint-based development with regular demos. QA testing on real devices. You see progress every two weeks.

05
Launch & Support

Store submission, go-live, performance check. Post-launch support included — we stay reachable after deployment.

An app people actually use — not one they download and forget.

Every package delivers a working, store-ready app — not a prototype that needs rebuilding. Strategy, design, development and store submission are included from the start. Need offline sync, complex integrations or native performance? We add exactly what you need — nothing more.

What makes this team different.

One team. No handoff loss.

Strategy, design and development in one house. No brief that gets lost between three agencies. No design that breaks in development.

We build to ship, not to demo.

Every app we build goes to the store, not into a presentation. Production quality from day one — tested on real devices, ready for real users.

Honest scope, honest pricing.

We tell you what your app actually needs — and what it doesn't. No feature bloat, no inflated quotes. The scope fits the goal.

Long-term partnership.

Apps need updates, new features, OS compatibility. We stay with projects after launch — many clients have worked with us for over 10 years.

Questions we get asked

Our packages start from €29,900 for an App Starter (MVP), from €54,900 for a full App System, and from €94,900 for an App Platform with complex architecture. Transparent scope, fair pricing.

It depends on the package. App Starter runs 10–12 weeks, App System 14–18 weeks, and App Platform 22–28 weeks. You get a fixed timeline in the proposal.

For most projects, Flutter. One codebase for iOS and Android, 30–40% lower cost, faster time to market. We recommend native only when platform-specific performance or hardware access demands it.

Yes. UX strategy, wireframes and complete UI design are part of every package. The same team designs and builds — no translation loss between design and code.

Bug fixes, OS updates, performance monitoring. App System includes 3 months post-launch support. App Platform includes an ongoing retainer option. We stay reachable.

Yes. We assess the current state, recommend rebuild vs. refactor, and give you a transparent plan. Sometimes a targeted improvement is smarter than a full rewrite.
