Mobile app scope
We reduce the app to the smallest useful release: core flows, roles, data needs, integrations, platform choices and launch constraints.

Direct answer
99 Francs provides mobile app development services for focused apps that need to ship cleanly.
The service covers app scoping, native iOS (Swift) and Android (Kotlin) builds, cross-platform development in Flutter or React Native, core flows, responsive states, integration assumptions, QA notes, App Store and Google Play submission, and a PWA path where a lightweight web app fits.
Build paths
Choose native or cross-platform by audience, budget and timeline.
Each page answers one build question directly — iOS, Android, Flutter or React Native — and routes into a scoped mobile development plan.

Native iPhone and iPad apps in Swift, built to Apple's guidelines and ready for the App Store.
Build for iOSAndroid App Development
Native Android apps in Kotlin, built to Material conventions and ready for Google Play.
Build for AndroidFlutter App Development

Build with FlutterReact Native Development
One JavaScript/TypeScript codebase for iOS and Android — fast iteration on a familiar React stack.
Build with React NativeWhat we build
Mobile development with product scope discipline.
The strongest mobile builds do not start with every possible feature. They start with the app surface that proves the product can be useful, trusted and used repeatedly.
Cross-platform build
We can build focused mobile apps in React Native or Flutter when one codebase is the practical path to iOS and Android.
Native app execution
When the product needs native behavior, we can scope Swift-based iOS work or platform-specific implementation around the critical flows.
Release-ready product surface
The build includes responsive states, forms, navigation, API handoff assumptions, QA notes and App Store preparation where needed.
Best fit
Use mobile app development when the app scope is focused enough to become a real release.
You need a focused app MVP
We build when the first version has a clear purpose: validate a workflow, support a web product, launch a companion app or prove a mobile-first idea.
The app should not become a huge platform
We keep the scope tight: fewer features, cleaner architecture, clearer flows and a build plan that prioritizes what users actually need first.
The design already exists
If you already have Figma screens, prototypes or a product design system, we can turn that into a working mobile app surface.
The app still needs product judgment
Development stays close to UX. We flag unclear flows, missing states and risky assumptions before they become expensive implementation problems.
Process
From app scope to working mobile product.
We keep the implementation tied to the intended product behavior: clear navigation, reliable states, practical integrations and a first version that can be tested.
Scope the first release
We review the product goal, design maturity, APIs, accounts, content, integrations, analytics, platform needs and App Store constraints.
Plan the app architecture
We define the mobile stack, data flow, navigation, state model, component structure and the parts that should stay out of v1.
Build the core flows
We implement the screens, navigation, forms, states, integrations and app behavior needed for a credible mobile MVP or companion app.
Test and prepare launch
We review responsive behavior, device states, bugs, content, analytics events, store assets and what the team needs after handoff.

Good mobile development starts with product clarity. These examples show the type of interface and workflow thinking that makes implementation easier to scope.

Questions teams ask before building a mobile app.
99 Francs develops focused mobile app MVPs, SaaS companion apps, AI app surfaces, internal tools and cross-platform mobile experiences when the scope is lean, product-led and realistic to ship.
Yes. We can scope React Native, Flutter or Swift depending on the product goal, platform needs, existing team and launch constraints.
Yes. If the app UX or UI is not ready, the project should start with mobile app design before development begins.
Not as the default offer. This service is best for focused MVPs, product companions, startup apps, AI app interfaces and lean mobile products where the first useful release matters most.
We build native iOS (Swift), Android (Kotlin), and cross-platform apps in Flutter or React Native. Each has its own page.
Yes. We prepare the build configuration, store listing assets and screenshots, help with review and policy preparation, and support the submission so the app reaches users on the App Store and Google Play — not just an internal test build.
Sometimes a Progressive Web App (PWA) is the right call — when reach, instant access and a single web codebase matter more than native device features or app-store presence. We scope a PWA when it genuinely fits, and recommend native or cross-platform when the product needs store distribution or deeper device capabilities.
The app itself is not usually a crawlable SEO surface, but the service page, app landing page, documentation, app store content, screenshots and case studies can be structured for search engines and answer systems.
