Mobile apps

Mobile apps for iOS and Android, from the first screen to the app stores

We design and build iOS and Android apps for customers and for teams in the field: cross-platform with React Native or native in Swift and Kotlin, together with the backend and admin panel behind them.

When does your business need a mobile app?

When people need your service on the go, often in the field, and a website is not enough.

  • Teams work in the field

    Drivers, technicians or instructors need jobs, checklists and documents on their phones.

  • Customers come back often

    Booking, ordering or tracking is faster in an app than on a website.

  • Paper still runs the job

    Forms, signatures and photos are collected on paper and typed in later.

  • Your product lives on the phone

    Maps, camera and notifications are part of the service.

  • Your app is outdated

    An old app with poor reviews, or one that breaks on new phones.

  • Data must reach the office

    What happens in the field should appear in your systems right away.

How much does a mobile app cost?

Every app starts with a written scope and price: a fixed price for a defined first version, then phases or hourly work. App store fees are paid by you, directly to Apple and Google.

What the price depends on

  • iOS, Android or both
  • Cross-platform or native
  • The backend and admin panel the app needs
  • Device features such as offline mode, GPS or payments
  • Integrations with your systems

Cross-platform or native?

We recommend one in the quote, based on what the app must do.

Cross-platform (React Native)

One codebase for iOS and Android: faster to build and maintain. Used for the CanterLope, logistics and City Parking apps.

Native (Swift and Kotlin)

Separate apps that use each platform fully, best for apps that push the device to its limits.

Mobile app questions

Usually both, so every customer or employee can use the app. With React Native, both come from one codebase; if all your users are on one platform, we can start there.
