iOS & Android App Development
Native and cross-platform mobile applications providing seamless, intuitive experiences on all devices.
Betty and Selim build mobile apps from Brussels with React Native: one codebase that feels native on both iOS and Android. That shortens time-to-market and keeps ongoing maintenance affordable, without compromising on the quality of the user experience. Your app keeps working without an internet connection and syncs data automatically when the signal returns, which matters for field teams and customers on the move anywhere in Belgium.

We connect the app to your existing databases and tools, including logins, push notifications, and real-time data, and we handle the full submission process for the Apple App Store and Google Play, from review preparation to responding to feedback. App development at Studio XL starts from €5,000. That starting price fits a compact app with the essential screens, for both iOS and Android.
The final price depends mainly on the number of screens and features, the integrations with your existing systems, and options like offline support or push notifications. You get a clear quote for the full project before we start.
What's Included

Connects to Your Existing Systems
We connect your app to your existing databases, tools, and services, including logins, push notifications, and real-time data, so it fits naturally into your workflow.
App Store Submission Handled

Case Studies
Our Process
Discovery
You send us your project, and Selim gets on a call with you to talk through your business and what the site needs to do. If it's a good fit, we lock in a start date.
Strategy + Design Direction
Betty maps out the structure and strategy, based on a short questionnaire and what you told us on the call. Selim turns that into a visual direction for your brand.
Creation
[OUR FAVORITE PART]Once the direction is signed off, Selim builds it: a website, an app, or whatever the project calls for. You'll see progress along the way, not just a reveal at the end.
Delivery
Once everything is approved, we hand over your files and set you up to run the site yourself. Then it's live, and it's yours.
Frequently asked questions
How much does it cost to build an app? +
App development at Studio XL starts from €5,000 for a compact app with the essential screens, running on both iOS and Android. The price depends mainly on the number of screens and features, the integrations with your existing systems, and options like offline support or push notifications. You get a clear quote for the full project upfront.
Will my app work on both iPhone and Android? +
Yes. We build with React Native: one codebase that delivers native performance on both platforms. You avoid paying for two separate development tracks, and every update reaches iPhone and Android users at the same time.
Do you handle App Store and Google Play publication? +
Yes, completely. We manage the full submission process for the Apple App Store and Google Play, including review preparation and responding to any reviewer feedback, so your launch goes smoothly and without unnecessary delays.
Does the app work offline? +
Yes, if your use case needs it. We build apps that keep working without signal and sync data automatically once the connection returns. Ideal for field teams or customers on the move. Offline support is one of the factors we scope in your quote.
How long does app development take? +
It depends on scope: a compact app with a few screens moves much faster than an app with many integrations and offline logic. The App Store and Google Play review process also adds time at the end. Your quote includes a concrete timeline with milestones.
