Mobile App Development Agency — iOS & Android
Ship a focused app that users keep — not a bloated one they delete.
We build iOS and Android apps with React Native, shipped lean and focused on the one thing users need. We've seen more apps die from feature creep than bad code, so we help you launch a sharp MVP, measure real usage, and add features only when the data asks for them.
Nearly 90% of apps fail — rarely from code, usually from building too much before validating anything. We build to launch and learn fast.
What's included
- Product scoping to define the smallest app that delivers the core value
- React Native build for iOS & Android from one codebase
- Analytics and event tracking so you see what users actually do
- App Store & Play Store launch support (ties into our ASO service)
- Post-launch iteration based on real usage, not opinions
How we work
We cut the scope to the core utility that solves one problem better than the alternative.
React Native for both platforms, with tracking so we can measure retention from day one.
Launch, watch onboarding and retention, and add features the data justifies.
Pricing
MVP builds typically from €6,000 depending on scope and integrations. We scope a fixed MVP after a discovery call.

App Development — frequently asked questions
How much does it cost to build an app in Europe?+
A focused MVP typically starts around €6,000 and rises with features, integrations, and backend needs. The biggest cost driver is scope — which is exactly why we push to launch lean first.
React Native or native (Swift/Kotlin)?+
React Native lets us ship both platforms from one codebase, which is faster and cheaper for most apps. For heavy graphics or deep hardware use we'll recommend native — we won't force the wrong tool.
How long does it take to build an app?+
A well-scoped MVP is often 6–12 weeks. The apps that balloon to 8 months are the ones that kept adding features before launch — we actively prevent that.
What makes most startup apps fail?+
Feature creep, building without an audience, and weak onboarding — not code quality. We scope the MVP tightly and wire analytics so you can validate before investing further.
Do you help get the app discovered after launch?+
Yes — our ASO service optimizes your store listing for organic installs, and we can run paid user acquisition alongside it.
