Our Process

From idea to App Store in 3 months

We put a testable build on your phone as early as possible. You use it, tell us what feels wrong, and we fix it before adding more features.

Step 1; Research & Prototype

User interviews, competitor teardown, and a clickable prototype you can test on your phone.

Step 2; Design the Core Flow

Visual design for the 3-5 screens your users will see most. Tested with real users before development starts.

Step 3; Build & Beta Test

Weekly TestFlight and Play Store beta builds. You and your test users provide feedback every sprint.

Step 4; Polish & QA

Performance tuning, device testing, and edge case handling. 12+ device models tested.

Straight Answers

What people ask before they build an app

From real sales calls. No softballs.

We decide per feature, not per project. Camera, GPS, and biometrics use native code for best performance. Shared screens like settings and profiles use React Native to save time and money. Most apps end up being a mix.

A focused MVP with 5-8 core screens runs EUR 40-70K. A feature-rich app with backend, admin panel, and both platforms runs EUR 80-150K. We give you an exact quote after a two-hour scoping session.

MVP in 10 weeks. Full-featured app in 14-16 weeks. Apple review adds 1-3 days, Google usually approves in under 24 hours. We submit with all guidelines pre-checked to avoid rejections.

We include 30 days of post-launch bug fixes in every project. After that, we offer monthly support packages starting at EUR 2K/month. Critical bugs get a hotfix within 24 hours.

Yes. We audit your current app, identify what is worth keeping, and rebuild the rest with modern frameworks. Your users keep their accounts and data. The app just gets faster and easier to use.

You do. Source code, design files, store accounts. We hand over everything. You can take the app to any developer for future work. No lock-in.
