Our expertise

Native or cross-platform mobile applications

We master the most requested technologies to build robust, fast apps.

Native development

High-performance apps written in each platform's own languages, for the best possible user experience.

  • iOS (Swift, SwiftUI)
  • Android (Kotlin, Jetpack Compose)
  • Maximum performance
  • Full access to device features

Cross-platform development

One codebase for iOS and Android, which cuts timelines and costs without lowering quality.

  • React Native
  • Flutter
  • Shared iOS and Android code
  • An interface that feels native

Which app does your business need?

An app makes sense when customers or staff use a service often and on the move. Think of a booking app, a customer area with notifications or a field tool for your technicians. However, if most visitors find you through Google, a fast website is sometimes enough.

We help you choose between native and cross-platform development. Native code gives the best performance and full access to the phone. Cross-platform code, with React Native or Flutter, shares one codebase between iOS and Android and therefore keeps the budget lower.

Full support, all the way to the stores

We prepare the mockups, build the app and test it on real devices. Then we handle submission to the App Store and Google Play, including store listings, screenshots and each store's rules. We also publish our own mobile applications, such as Company Belgium BCE.

After launch, a maintenance contract keeps up with new iOS and Android versions, fixes bugs and adds features. We also take care of GDPR: consent, minimal data collection and data security. As a result, your mobile applications stay compatible and secure.

The budget depends on the screens, the features and the links to your systems. Our custom plans, which cover mobile applications, start at €79/month excl. VAT with a 24-month commitment. We send a free quote within 24 hours.

Often yes, because your audience splits across both systems. A cross-platform approach covers iOS and Android with a single codebase. We look at your audience before recommending an option.

We do: the store listing, screenshots, description and replies to Apple and Google reviews, right up to go-live.

Each new iOS or Android version can affect your app. Our maintenance covers updates, bug fixes and new features, at a pace we agree on together.

Yes, depending on your needs: the app can store some data on the phone and sync once the network returns. We define this behaviour during the UX phase, because it shapes the whole architecture.
