Mobile development
iOS & Android apps built with Flutter
From concept to App Store and Google Play - we design and build high-quality mobile applications that work natively on both platforms. One codebase, two stores, full delivery including store submission and landing page.
Many mobile app projects qualify for the Innovation Tax Credit (CII) - ask us during your initial exchange.

Two use cases
For your customers or for your teams
Customer-facing apps
A dedicated mobile app is the most powerful extension of your brand - directly on your customers' devices.
Internal business tools
A bespoke app for your teams means operational efficiency - purpose-built tools instead of generic software.
Our approach
What we bring to every mobile project
iOS & Android from a single codebase
We build with Flutter, which means your app runs natively on iOS and Android from a single codebase. One development cycle, two stores, significant cost savings.
Native performance
Flutter compiles to native ARM code - not a web wrapper. The result is a fast, smooth, responsive app that feels at home on both platforms.
AI-enhanced features
We integrate AI where it genuinely improves the experience - natural language inputs, document scanning, personalised recommendations, intelligent automation.
Push notifications & offline mode
Direct push notifications for targeted user communication, and offline capability so your app works even without a network connection.
Full store deployment
We manage the entire App Store and Google Play submission process - screenshots, descriptions, privacy policies, app review and first publication.
Structured, maintainable code
We apply clean architecture principles from day one - separation of concerns, testable code, clear documentation. Your app is built to grow, not to be rewritten.

FAQ
Mobile development - your questions
What types of mobile apps do you build?
We build all types of mobile applications: B2C apps (available on the App Store and Google Play), B2B internal tools, marketplace platforms, AI-powered apps, healthcare apps, wellbeing, education, entertainment and more. If it needs to be on a phone, we can build it.
Why Flutter rather than native Swift or Kotlin?
Flutter gives you native performance on both iOS and Android from a single codebase, which typically halves development time and cost without sacrificing quality. For most apps, the result is indistinguishable from fully native - and for several of our clients, Flutter has been the right choice for complex, AI-powered applications.
Do you handle the App Store and Google Play submissions?
Yes - completely. We handle the developer account setup, prepare all required assets (screenshots, icons, feature graphics), write the store descriptions, configure privacy policies and manage the review process with Apple and Google. This is a standard part of our delivery, not an extra.
How long does it take to build a mobile app?
A focused MVP typically takes 3 to 6 months depending on complexity. More complex apps with AI integrations, payment systems or third-party API integrations can take 6 to 12 months. We always start with a scoping phase to define a realistic timeline before any commitment.
Can you integrate in-app purchases and subscriptions?
Yes - we have extensive experience with both Apple In-App Purchase and Google Play Billing, as well as RevenueCat for cross-platform subscription management. We have implemented these for several live applications.
Do you offer ongoing maintenance after launch?
Yes - we offer maintenance contracts covering component updates, OS compatibility as iOS and Android evolve, bug fixes and regular new builds published to the stores to maintain freshness. Several of our clients have been with us for several years.
Can you integrate specific features like geolocation or payments?
Yes - we have experience with a wide range of integrations: geolocation, maps, payments (Stripe, RevenueCat, Trust Payments), authentication (Pro Santé Connect, OAuth), cloud services (Firebase, Google Cloud, AWS), push notifications (OneSignal), electronic signatures (YouSign) and more.
