Mobile apps for iOS and Android, from one codebase

For your crew on site, your customers on the road or a product of your own that you want to sell. We take on the whole route, from the first sketch to the updates after launch.

Work orders

The phone as a real workplace

We build apps with React Native and Expo: one codebase that runs on iPhone and Android as a real native app, with the speed and the feel users expect. Push notifications, camera, GPS, offline use and payments inside the app all belong to it. The app is often the extension of a central platform: your crew fills in work orders on the phone and at the office everything comes together in the dashboard right away.

That single codebase is mostly a financial choice. Every feature is designed once, built once and tested once. Against two separate native apps that quickly saves half the budget, and your users never notice.

Almost every app also needs a back end: a database, accounts and a place where you sit at the controls as the administrator. We build that too, together with a web dashboard where you manage users, content and numbers.

How we work

From sketch to app in the store

You test on your own phone from the first build week and follow the app all the way into both stores.

  1. Week 1

    Screens & proposal

    We settle which screens and device features you need. Within 24 hours you get a fixed proposal for iOS and Android together.

  2. Week 1–2

    Design on real screens

    You see and feel the app at iPhone and Android size before a single line of code is written.

  3. Week 2–7

    Build & test along

    From the first build week the app sits on your own phone through TestFlight and an internal test build. A new version every week.

  4. Week 8

    Publication

    We arrange the developer accounts, screenshots, store copy and the review at Apple and Google.

  5. After that

    Over-the-air updates

    After launch we send out small improvements without a waiting period. They reach your users within the hour.

Ready for both app stores

An app in both stores, on developer accounts that are in your name. The code is yours, the user data sits in your database and you can walk to another party with all of it at any moment.

We build in crash monitoring and analytics as standard, so we see problems before your users report them. And through the web dashboard you manage your own content, users and numbers without having to knock on our door.

What is in your mobile app

iOS, Android and the management behind the scenes belong to one whole. This comes as standard.

  • App in the App Store and the Play Store
  • One codebase for iOS and Android
  • Push notifications, camera, GPS and offline use
  • Back end with database and user management
  • Web dashboard to manage your app
  • Crash monitoring and analytics
  • Store copy and screenshots
  • Developer accounts and code in your name

Questions about mobile apps

Do I need separate apps for iPhone and Android?

No. We build one codebase in React Native that runs on both platforms as a real native app. Every feature is built once and works on iPhone and Android right away, which almost halves the budget against two separate apps.

Can I ship updates without waiting for a review every time?

For most changes, yes. Improvements to screens, copy and logic go out over the air and reach your users within the hour. Only big changes, such as new native features, pass the store review again.

What does it cost to have a mobile app built?

That depends on the size: the number of screens, the connections and what is needed at the back end. After a first conversation you get a fixed proposal with price and timing within 24 hours. Thanks to the shared codebase you never pay twice for iOS and Android.
