On a mobile project with an agency, your brief passes through 3 or 4 hands before reaching the code. Salesperson, project manager, designer, junior developer. Any scope change means a change request. And the code is often delivered by someone who knows neither your business nor your constraints.
Here, you talk directly to the person writing the code. Feedback is implemented in hours, not days.

Bulk message and post deletion app for Discord, Slack, Twitter, Reddit, and Instagram. Privacy-first architecture: credentials encrypted and stored locally on the device, zero data on remote servers. Live on App Store and Google Play from a single React Native codebase.
Unpost shipped on Apple App Store and Google Play Store from a single React Native codebase. One team, one version, evolving in parallel across both platforms.
Privacy-first architecture: every account credential (Discord, Slack, Twitter, Reddit, Instagram) is encrypted and stored locally on the device. Zero data on external servers.
30 minutes over video. We talk about your app, your target market, and your budget. I give you an honest read on which tier fits (MVP, Standard, or Advanced) and what's feasible in your range.
Interactive mockups delivered in 10 business days. You test on your own phone via TestFlight (iOS) and Android builds. Scope validated before main development. Three milestone payments: 30% / 40% / 30%.
Weekly sprints with demos on your phone. Full Apple App Store and Google Play Store submission included. 30 days of support after launch.
European mobile users have specific expectations. GDPR compliance, support in their language, local payment methods. An app designed for the US market and hastily adapted shows immediately.
I design for Europe from the first mockup: GDPR by design (explicit consent, right to erasure, data hosted in Europe), multilingual interface (French, English, German at minimum), local payments (Stripe France, SEPA, Apple Pay, Google Pay), and cross-border tax compliance if your customers go beyond France.

€5,000 to €12,000 for a simple MVP, €12,000 to €25,000 for a complete pro app, €25,000 to €50,000+ for a custom complex app (marketplace, mobile SaaS, multiple integrations). The 3 tiers are detailed above on this page. Exact quote after our discovery call.
React Native is the standard for cross-platform apps in Europe. Native performance, mature ecosystem, and the same frontend developers as for the web. Unpost, for example, handles 5 API integrations (Discord, Slack, Twitter, Reddit, Instagram) from one React Native codebase, on iOS and Android. Flutter is solid but has a smaller community and a less mature library ecosystem for European integrations. Native (separate Swift and Kotlin) doubles the cost and timeline. For 95% of projects, React Native is the right choice.
No. A single React Native codebase generates two native apps, one for iOS and one for Android. Users see no difference from a pure native app: same fluidity, same features (camera, GPS, push notifications, payments). The difference is in your budget and timeline, not in the user experience.
I do. Full submission to the Apple App Store and Google Play Store is included in every tier. Developer account creation if needed, listing configuration, screenshots, descriptions, and Apple and Google review handling.
Apple developer account: USD 99/year. Google developer account: USD 25 lifetime. These fees are paid directly by you to Apple and Google, not through me. For in-app payments: 30% the first year, then 15% after (App Store and Play Store apply the same commissions). For external payments (Stripe, SEPA transfers), zero store commission.
30 days of free support included in every tier (bug fixes, minor adjustments, monitoring). After that, monthly maintenance starting at €300/month for ongoing support. If you prefer to handle it yourself, the code is on your Git repository and you can hire another developer.
No. I work with companies across Europe: France, Belgium, Switzerland, Luxembourg, Germany, Austria. I communicate in French, English, and German. All exchanges happen remotely via video, email, and messaging. Distance has no impact on quality or responsiveness.
Tell me what you want to build. I'll tell you exactly which tier fits, what it'll cost, and how long it'll take.
