Why a mobile app in Geneva

Switzerland has one of the highest mobile penetration rates in Europe: over 96% of the population owns a smartphone, and the Swiss spend an average of 3.5 hours per day on their apps. In Geneva, an international and highly connected city, this reality is even more pronounced. Your clients, employees, and partners have their phones in hand constantly. Not being there means leaving the field open to your competitors.

In a dense Geneva market — finance, healthcare, education, commerce — a mobile app represents a tangible competitive advantage. It positions you as a modern, accessible, and customer-oriented company. A well-designed app improves retention, simplifies the purchasing journey, and creates a direct channel that depends on neither social networks nor advertising.

Above all, a mobile app works for you 24/7. It's a lead generation tool that never sleeps. Our client Lumina App is proof of this: it generates qualified contacts continuously, even at 3 AM, without human intervention.

Flutter & React Native: one app, two platforms

Developing two separate apps — one for iOS, one for Android — means two codebases, two teams, two budgets. With Flutter or React Native, we write a single codebase that runs natively on both platforms.

Flutter (Dart/Google) is our preferred technology. Excellent performance, smooth animations, pixel-perfect rendering, and the ability to also target desktop (macOS, Windows, Linux) and web from the same codebase. It's our default choice for new projects.

React Native (JavaScript/React) is an excellent alternative when your web ecosystem is already in React/Next.js — code and skills are shared between your site and your app.

In both cases, you benefit from a 30 to 40% cost reduction compared to separate native development, with near-identical performance.

— Méthode

From idea to store in 4 steps

01

Discovery & prototyping

We understand your users and goals. Interactive Figma prototype testable on your phone. UX validation before investing in development.

02

Native UI design

Respect for Human Interface Guidelines (Apple) and Material Design (Google). Navigation, gestures, typography — every detail tailored for the target platform.

03

Development & testing

2-week sprints with regular demos. Testing on the most used real devices in Switzerland. Automated, manual, and performance tests. Stable app, even on older models.

04

Store publication + ASO

Developer accounts, screenshots, store listings, submission, Apple/Google reviews. ASO optimization for visibility in store search results.
