Mobile App Development

A successful mobile app is judged by usage: opens fast, used often, useful every time. LaMeDuSe designs and builds custom mobile applications, from product scoping to store release.

The problem you're facing

Many mobile apps are poorly wrapped websites: slow to launch, unusable offline, abandoned after three opens. Mobile development requires specific choices : and a partner who masters them.

Our answer

We build native or cross-platform applications depending on the intended usage: performance, sensors, offline mode. Product scoping first defines what the app must do in the user's hand, then the stack follows : not the other way round.

What LaMeDuSe takes care of

  • Product scoping and user journeys
  • UX/UI design adapted to target platforms
  • iOS and/or Android application (native or React Native)
  • Secure backend API and data synchronisation
  • App Store and Google Play release
  • Version tracking, fixes and evolution

Our methodology

  1. 1

    Product discovery

    Workshops with your business teams to turn the need into scope, user journeys and measurable success criteria.

  2. 2

    Design & architecture

    Wireframes, technical architecture and documented stack choices: every decision is argued and reversible.

  3. 3

    Iterative development

    Regular releases to staging environments, systematic code reviews and demos at every iteration.

  4. 4

    Production & operations

    Automated deployment, monitoring, bug fixes and continuous improvements with the same team.

Relevant technologies

React & Next.jsNode.js, Go, PythonPostgreSQL, RedisKubernetes & DockerCI/CD GitHub Actions

Security

Systematic code review, secrets management, monitored dependencies and security testing built into the development cycle : security is a starting requirement, not an option.

Hosting & infrastructure

We host your applications on our own European infrastructure (France, Germany, Switzerland): development and operations are carried by the same group, with no dependency on US cloud.

Maintenance

Application maintenance contracts covering bug fixes, upgrades, feature evolution and user support : the team that designed the software is the team that keeps it alive.

Why LaMeDuSe

We build mobile applications on our own European backend: your users' data stays under European jurisdiction : a GDPR compliance argument few agencies can make.

Frequently asked questions

Not always. Cross-platform (React Native) covers most needs with a single codebase. Native is justified for demanding performance, sensor or system-integration requirements. We recommend based on usage, not fashion.

From the low tens of thousands of euros for a simple app to six figures for a full platform. Product scoping allows precise pricing, and an MVP validates usage before you invest everything.

We handle publication on your App Store and Google Play developer accounts, with assets, store listings and follow-up of Apple's and Google's validation processes.

Data is hosted on our European infrastructure, minimised by design, and consents are managed in the app. Compliance is built into development, not bolted on afterwards.
