Mobile apps
We build native iOS and Android apps (or cross-platform, when that is more feasible) and publish them on the App Store and Google Play.
What you get
Before any code, we agree together on what the app must do and for whom: which features are essential, what it uses from the phone (camera, notifications, location, QR code scanning), whether it must work offline and which systems it connects to. Based on that, we recommend the approach: native apps in Swift and Kotlin, when performance and full access to the phone matter, or a single cross-platform codebase, with Flutter or React Native, when that gets you to both platforms faster and more efficiently.
Then we build the app end to end: design, development, the backend and API, testing, publishing on the App Store and Google Play, and the updates after launch. If you already have a web platform, the app uses the same data, so users find the same information wherever they work.

Frequently asked questions
Native or cross-platform app?
A native app, written in Swift for iOS and in Kotlin for Android, has the best performance and full access to the phone's features. A cross-platform app, built with Flutter or React Native, uses a single codebase for both platforms and reaches users faster. We recommend the more feasible option once we agree on what the app must do.
Do I need an app, or is a good mobile website enough?
An app is worth it when users come back often, when you need notifications, the camera, code scanning or offline operation. For presentation and information, a fast, mobile-friendly website is often enough. We will tell you honestly which option fits you.
Who takes care of publishing on the App Store and Google Play?
We do. We prepare the store listing (description, screenshots, privacy information), submit it for review and handle Apple's and Google's requirements. We help you create the developer accounts, so the app is published under your company's name, or we publish it directly from our own accounts, so you don't have to deal with enrolling your company.
Can the app connect to the platform or website I already have?
Yes. The app uses the same backend or an API built for it, so the data is the same in the app and on the web. If you don't have a backend yet, we build it.
Does the app work without internet?
Yes, where it makes sense. The data the user needs is kept on the phone, and when the connection is back, the app syncs automatically with the server.
What happens after launch?
We update the app for new iOS and Android versions, fix issues and add new features, in stages. Every project comes with at least a one-year warranty, and complex projects with at least two years.
