One app for iPhone and Android
Most businesses need their app on both iPhone and Android. Building two separate native apps doubles the work. With cross-platform development, a single code base runs on both, which usually reduces cost and makes updates simpler.
Read more about the specifics of each platform: iOS app development for iPhone and iPad, and Android app development for Google Play. Because we also build web applications and websites, your app can share the same back-end, user accounts and data as your website.
We focus on cross-platform development. If your app depends on advanced device features where fully native development (Swift for iOS, Kotlin for Android) is clearly better, we will say so at the start.
Who this service is for
- Start-ups launching a first version of their app on iOS and Android.
- Businesses that want an app for their customers, connected to their existing systems.
- Companies with a web platform that need a companion mobile app.
Our mobile app services
iOS & Android apps
One cross-platform code base for iPhone, iPad and Android devices.
App UX & UI design
User journeys and interfaces designed for small screens and quick actions.
Back-end & APIs
Secure APIs, user accounts and admin panels, shared with your website when relevant.
Notifications & integrations
Push notifications, payments, maps and third-party services.
App Store & Google Play
Store listings, submission and review handled with your developer accounts.
Maintenance
Updates for new iOS and Android versions, fixes and new features.
Native, cross-platform or progressive web app?
Native apps
Written separately for iOS (Swift) and Android (Kotlin). Maximum access to device features, but two code bases to build and maintain.
Cross-platform apps
One code base published to both stores. Our default: a native-feeling app with less cost and simpler updates.
Progressive web apps (PWA)
A web app that can be installed from the browser, without the app stores. Useful for simple tools and internal apps.
How we work
A clear, collaborative process — with one point of contact from the first call to launch and beyond.
Idea & scope
Users, core features and technical approach defined together.
Design & prototype
An interactive prototype to test the experience before coding.
Development & testing
Iterative development with test builds on your own phone.
Launch & evolve
Store publishing, monitoring and new features based on real usage.
Technologies
Cross-platform (iOS & Android) JavaScript REST APIs Push notifications App Store Connect Google Play ConsoleWhat affects the cost
Every project is quoted individually after a short discovery call. The main factors are:
- The number of screens and features in the first version.
- Back-end needs: accounts, data, admin panel.
- Integrations such as payments, maps or existing systems.
- Device features required (camera, location, offline mode).
- Maintenance after launch.
What you receive
- Apps published on the App Store and Google Play under your accounts.
- Source code and documentation.
- An admin panel or back-end where needed.
- Optional maintenance for OS updates, fixes and new features.
Frequently asked questions
Should I build a native app or a cross-platform app?
For most business apps, cross-platform covers iOS and Android with one code base and lower cost. Native development is worth it when an app relies heavily on advanced device features or very demanding graphics.
Do I need a website as well as an app?
Usually yes: your website helps people find you on Google, and your app serves engaged users. We can build both on the same back-end.
Can you publish my app on the App Store and Google Play?
Yes. We prepare the store listings and handle submission and review using your developer accounts, so the apps belong to you.
How much does it cost to build an app?
It depends on the number of screens, features and integrations. After a scoping call we send a clear proposal, and we can start with a focused first version.
What happens after launch?
We monitor the app, fix issues, keep it compatible with new iOS and Android versions and add features as your users grow.
