Mobile App Development Company in France

Choose a mobile app development company that can prove three things for the French market: shipped apps live on both the App Store and Google Play, documented RGPD-compliant data handling with EU-region hosting, and proper French localisation rather than machine translation. SpiderHunts Technologies has delivered over 1,000 projects since 2015 and builds native iOS, native Android, Flutter and React Native apps for clients across France, Europe, the UK and the USA. Every engagement starts with a free scoping call and a fixed written quote in euros.

In France, a cross-platform MVP typically costs from €15,000 to €35,000 over 6 to 10 weeks. A production app with a custom backend, payments and third-party integrations generally runs €35,000 to €80,000, while fully native iOS and Android builds for complex products range from €50,000 to €120,000 or more. Budget an additional 15 to 20 percent of the build cost per year for maintenance, OS updates and store compliance.

Yes. We build apps to RGPD requirements by default: EU-region data hosting, explicit consent flows that meet CNIL guidance on tracking and cookies, data minimisation in the mobile SDK layer, documented retention periods, and working data-export and deletion endpoints. Where an app uses AI features we also assess obligations under the EU AI Act, including the transparency notices users are entitled to when interacting with an AI system.

Cross-platform with Flutter or React Native is the right default for most French businesses, because one codebase covers iOS and Android at roughly 60 to 70 percent of the cost of two native builds. Choose native when the app depends heavily on device hardware, needs demanding graphics or real-time processing, or must adopt new OS capabilities the moment Apple or Google ships them. We recommend the option that fits the product, not the one that fills more billable hours — see our Flutter vs React Native comparison for the detailed trade-offs.

Yes. We work with businesses across France including Paris and Île-de-France, Lyon, Marseille, Toulouse, Nice, Nantes, Bordeaux, Lille, Strasbourg and Montpellier. Delivery is remote-first with overlapping Central European Time working hours, weekly demos, and a named delivery lead, so distance does not slow the project down.

Yes. Proper French localisation goes beyond translating strings: it covers fr-FR formatting for dates, numbers and currency, tone decisions such as vous versus tu, text expansion in the UI because French runs longer than English, French-language App Store and Google Play listings for the France storefront, and payment methods French customers expect including Carte Bancaire. We treat localisation as part of the build, not an afterthought.

A focused cross-platform MVP typically takes 6 to 10 weeks from kickoff to store submission. A production app with a custom backend, payments and integrations usually takes 10 to 18 weeks, and complex native builds 14 to 24 weeks. Add roughly one to two weeks for App Store and Google Play review cycles, which is where unprepared teams most often lose time.

Yes. Every build includes a post-launch warranty period, and we offer ongoing maintenance retainers covering bug fixes, iOS and Android version updates, security patches, store policy compliance, and feature work. Mobile apps break silently when a new OS version ships, so ongoing maintenance is not optional for a product you depend on.
