One app for iOS, Android and web — launch faster, spend less

A mobile app that works everywhere

A mobile app that works everywhere — iOS, Android and web — delivered fast and on budget. With our cross-platform expertise, we develop from a single TypeScript codebase, letting you reach every platform without multiplying costs. The same craft quality as large Swiss agencies, with the agility and efficiency of a 4-person senior team augmented by AI. Your budget goes into code, not overhead.

At Appik Studio, we adopted React Native from its early days. Our team has been working with React Native since its earliest versions. We've watched the ecosystem mature and evolve into the solution of choice for demanding companies that want speed without compromising quality. Our apps frequently incorporate artificial intelligence integration to enhance the user experience, and every project benefits from premium UX/UI design crafted to maximize engagement.

Our Mobile Expertise

One codebase, all platforms

Develop for iOS, Android, and the web simultaneously. With React Native and Expo, we share up to 95% of code across platforms. Result: you reduce costs by 30 to 40% compared to separate Swift/Kotlin native development, while maintaining a native, fluid user experience.

Guaranteed native performance

React Native compiles to native code. Your users will see no difference from an app built with Swift or Kotlin. Smooth 60fps animations, full access to native APIs (camera, Bluetooth, geolocation, NFC), and exemplary responsiveness.

Instant updates (OTA)

With Expo Updates, deploy fixes and new features without going through Apple and Google stores. Your users receive updates in real-time, allowing you to iterate quickly and respond to market feedback.

Mature and sustainable ecosystem

10 years of React Native, 8 years of Expo. A massive developer community, battle-tested libraries for every use case: Bluetooth, camera, in-app payments, push notifications, geolocation, biometric authentication, and more.

Technologies We Master

Mobile Projects Delivered

Our mobile applications are deployed across Switzerland and Europe:

• Le Temps — Development of the new mobile app for the leading daily newspaper in French-speaking Switzerland, based on their internal design. Full accompaniment: co-development with the internal team, knowledge transfer and onboarding to enable Le Temps developers to take over autonomously.

• Pneumoscope — Connected stethoscope via mobile app, developed with HUG's spin-off Onescope. Bluetooth connection, AI algorithms executed directly on the smartphone for real-time analysis of respiratory pathologies.

• Equipass — Mobile-first web application for digital equine passports, built for an international equestrian sports federation based in Lausanne. Identification data, health records, movement traceability — serving 137+ national federations.

• Detectra — Mobile app and web dashboard for remote monitoring of inflammatory arthritis, in collaboration with UNIL-CHUV Rheumatology. Computer vision, digital biomarkers and patient-reported outcomes.

• Time District — Mobile marketplace for watch collectors in Switzerland, UK, and Europe. Physical authentication, Blockchain certificates, verified ecosystem for secure transactions.

• Smatch — Sports meetup app in Switzerland. Matching algorithm based on sports level, availability, geolocation. Integrated chat for organizing meetups.

• ApiZoom — Parasite detection in beehives using Deep Learning. EPFL and Swiss company ApiZoom collaboration. Photo → AI analysis → instant diagnosis.

• CervixCheck — Cervical cancer detection aid. Collaboration with EPFL's LTS5 laboratory and Geneva University Hospitals (HUG). Secure data collection and risk factor classification.

• ClearSky — Edge AI application for phone call analysis. Artificial intelligence executed entirely on the smartphone for maximum privacy.

Our Mobile Development Process

1. Consultation and scoping

We analyze your project during a free consultation: business goals, target audience, key features, technical constraints. Together we define the MVP scope.

2. UX/UI Design

Our designer creates wireframes then high-fidelity mockups on Figma. Every screen is designed to maximize engagement and user satisfaction.

3. Agile development

2-week sprints with regular demos. You follow progress in real-time and can adjust priorities at each iteration.

4. Testing and quality

Unit tests, integration tests, testing on real devices (iOS and Android). We guarantee a stable and performant application before each release.

5. Deployment and store submission

Publication on the App Store and Google Play Store. We handle screenshots, descriptions, ASO keywords, and the review process.

6. Support and maintenance

Security updates, compatibility with new iOS/Android versions, crash monitoring, feature evolution. Your application stays performant over time.

Frequently Asked Questions

How much does mobile app development cost? At Appik Studio, expect from CHF 25,000 for a functional MVP, up to CHF 150,000+ for complex applications with advanced integrations (AI, IoT, payments). Every project is unique — contact us for a personalized quote. See also our detailed guide: How much does a mobile app cost in Switzerland?

How long does it take to develop an app? An MVP can be delivered in 2 to 3 months. A full-featured application typically requires 4 to 6 months. With Expo and React Native, we develop for iOS and Android simultaneously, significantly accelerating the timeline.

Will my app work as well on iOS as on Android? Absolutely. React Native compiles to native code for each platform. The user experience is identical to a natively developed application. We test on real iOS and Android devices to guarantee high quality.

Can I update my app without going through the stores? Yes, thanks to Expo Updates (OTA). Content and business logic updates can be deployed instantly. Only native code changes require a new store submission.
