Mobile app development for iOS and Android

We design and build mobile apps for iOS and Android from a single codebase, so you launch on both app stores sooner and maintain one product instead of two.

What our mobile app development covers

Our apps connect to the same back office as your website, so customers, orders and content stay in sync everywhere.

  • Cross-platform apps

    One codebase for iOS and Android using Flutter or React Native.

  • Ordering and loyalty apps

    Let customers browse, order, pay and earn rewards from their phone.

  • Booking and service apps

    Appointments, reminders and payments in a few taps.

  • Staff and delivery apps

    Field teams and riders get jobs, routes and updates in real time.

  • Push notifications

    Bring customers back with timely, targeted notifications.

  • App Store and Google Play launch

    We handle builds, store listings, screenshots and review submission.

Mobile app development questions

Have a question that is not here? Ask us directly.

How long does it take to build an app?

A focused first version usually takes eight to twelve weeks, including design, development, testing and store submission.

Do you build for both iOS and Android?

Yes. We use Flutter or React Native, so one codebase runs on both platforms.

Will you publish the app to the stores?

Yes. We prepare the listings and submit to the App Store and Google Play under your developer accounts.

Can the app work with my existing website?

Yes. We connect the app to your website or back office so products, orders and users stay in sync.
