We build intuitive, fast mobile apps tailored to how your customers or teams work.
Apps built for your end users, from the first launch to everyday use. They stay smooth, clear and pleasant to browse on every screen.
Mobile tools for your teams, available where the work happens. They bring data, processes and communication into a single app.
Mobile stores to sell online and keep your customers coming back. The journey stays fast, from catalog to checkout.
Book services and slots online, at any hour. The app confirms, reminds and collects payment without manual work.
Order and track deliveries from pickup to arrival. Every step stays visible for both the customer and the driver.
Connect your users and keep your community active. The app gathers discussions, groups and events in one place.
Specialized apps shaped for the needs of your sector. They fit your business processes and your own rules.

1. User login
Secure sign-in via email, social login or biometrics, with session management across devices.
2. Push notifications
Real-time alerts to inform, re-engage or retain your users, even when the app is closed.
3. Geolocation
Precise location to offer services, directions or deals tailored to the user's position.
4. Mobile payment
Secure in-app payment by card, digital wallet or recurring subscription.
5. Built-in chat
Instant messaging between users or with your support team, right inside the app.
6. QR code scan
Fast QR code scanning to identify, validate or connect a product, ticket or account.
7. Offline mode
Works even without a connection, syncing automatically as soon as the network returns.
8. API synchronization
Real-time data exchange with your existing systems via a secure API.
A good mobile app is judged in the hand: speed, natural gestures and reliability even offline. Together we choose between native and cross-platform development based on your performance needs and budget, with no dogma. From design to publishing on the App Store and Google Play, we handle the full cycle, then track real usage to refine the experience release after release.

1. Native or cross-platform
We advise the most suitable technology, from pure native for demanding needs to cross-platform to cover two systems with a single shared codebase.
2. Polished experience
Smooth animations, short response times and respect for iOS and Android conventions, for an app that inspires trust from the first tap.
3. Offline mode
Your users keep working without a network, with automatic and reliable data synchronisation as soon as the connection returns.
4. Useful notifications
Relevant, well-paced push notifications that bring users back at the right moment, without overwhelming them or triggering uninstalls.
5. Store publishing
We handle listing preparation, compliance with store rules and submission, avoiding the rejections and delays that slow down a launch.
6. Usage analytics
We instrument the app to understand real journeys and drop-off points, so we can prioritise the improvements that genuinely matter.
A successful mobile app is judged in the hand: it starts fast, responds to the finger and stays reliable even without a network. We build iOS and Android apps around that real use, whether it is a consumer app or a tool for your teams in the field. These apps can handle accounts, payments, notifications and data synced with your systems. Depending on your performance needs and your budget, we choose with you between native and cross-platform development, with no bias.
This technical choice is not trivial. Native (Swift, Kotlin) makes full use of each phone for demanding graphics or hardware needs. Cross-platform (Flutter, React Native) covers both systems from a single codebase, which cuts cost and time. In both cases, the architecture stays modular so new features can be added later. We decide by your priorities, never by habit, then design an interface that respects the conventions of iOS and Android.
We begin with clickable mockups to validate the screens and gestures before coding. Development moves through testable versions you install on your own phone, which makes feedback concrete. We take care of offline mode from the start: the app keeps working without a network and syncs the data as soon as the connection returns. Performance (smoothness, response time, battery use) is measured on real devices.
Then comes publishing, often the trickiest part. We prepare the listings, the visuals and compliance with Apple and Google rules, then submit the app to avoid rejections and delays. We also handle the permissions and data protection the stores require. The developer accounts stay in your name, so you keep ownership. After launch, we track real usage, fix bugs and adapt the app to new versions of iOS and Android, release after release.
FronxSolutions is a Belgian software studio, and your apps are built by experienced people who know the constraints of both platforms. We work transparently: you test each version, you set the priorities and you follow progress without having to guess. The source code, the repositories and the publishing accounts belong to you. Nothing is locked to us, and everything we produce can be taken over by another team.
So we prefer to earn your loyalty through the work rather than through a commitment that holds you. Based in Belgium, we stay close, reachable and clear about our technical choices as well as the costs. We advise you honestly, even when that means a simpler solution than a full native app. We also stay available for your questions between releases. After launch, we keep handling fixes, updates and improvements, at the pace of your users.

Not necessarily. A cross-platform approach can cover both systems from a shared codebase, which reduces cost and time to market. For very demanding graphics or hardware needs, native development remains preferable. We decide together based on your priorities.
Launch is only a beginning. We keep up with operating system versions, fixes, security updates and feature evolutions. Thanks to usage analytics, we propose concrete improvements grounded in how your users actually behave, not guesses.
Yes. The app can connect to your web platforms, databases and business APIs through secure services. Your mobile data stays synchronised with the rest of your information system, avoiding isolated silos and manual re-entry of the same records.
We guide you through creating and configuring your developer accounts, which stay in your name so you keep full ownership. We then prepare the listings, visuals and submission to ensure a compliant publication with no unpleasant surprises.
