Mobile app development for iOS and Android

Why build a mobile app?

Be on your customers’ home screen. An app keeps your brand one tap away and brings users back with push notifications.

Offer a smoother experience. Native features such as the camera, location, payments and offline mode make everyday tasks faster.

Save time for your teams. Field apps, inspections, orders or time tracking: a business app replaces paper and spreadsheets.

One codebase, two platforms. Cross-platform development with Flutter or React Native cuts cost and time to market.

What our mobile app development includes

A complete project, managed by one team:

  • UX/UI design with a clickable prototype before development
  • Development for iOS and Android, with automated tests
  • The back end, admin dashboard and API integrations
  • Publication on the App Store and Google Play
  • Training, documentation and 3 months of warranty

You own your app: the source code, developer accounts and data belong to you.

Launching a mobile app MVP and growing it

Start with an MVP, then grow

We help you launch a first version, the MVP, with the features that bring the most value. Real users test it quickly, and their feedback guides the next versions.

Your app often needs a web side too: a customer portal, an admin dashboard or a SaaS platform. We build both with our custom web application development team.

Mobile app development cost: how much is an app?

The cost of a mobile app depends on the number of screens and features, the back end required, the integrations with your tools and the platforms targeted. Cross-platform development keeps the budget lower than two separate native apps.

After scoping workshops, you receive a fixed-price quote split into milestones, with no VAT or sales tax added.

Pay in 3 interest-free installments for projects over $1,000.

        Mobile app development: frequently asked questions

        How much does it cost to develop a mobile app?

        The cost depends on the number of features, the back end, integrations and the platforms targeted. You receive a fixed-price quote after scoping workshops, with no VAT or sales tax added.

        How long does it take to build an app?

        A first version (MVP) usually takes three to five months, including design, development, testing and publication. Complex apps take longer.

        Native or cross-platform: which should I choose?

        Cross-platform frameworks such as Flutter and React Native cover most needs with one codebase for iOS and Android. Native development is useful for apps that rely heavily on specific device features.

        Do you publish the app on the App Store and Google Play?

        Yes. We prepare the store listings and handle the submission, in your own developer accounts, until the app is approved.

        Who owns the source code?

        You do. The source code, the developer accounts and the data belong to you from the start.

        Do you maintain the app after launch?

        Yes. We offer maintenance plans to keep your app compatible with new OS versions, fix bugs and add new features.
