For SMEs, startups and business teams
Mobile app development, from the screen to the server.
A mobile app is screens, but also APIs, a back office, notifications, user accounts and publishing on the App Store and Google Play. We design and build all of it, for your customers or for your teams in the field, and stay responsible for it working after launch.

When a mobile app is worth it
Your field teams work on paper
Job sheets, photos, signatures, stock counts: an app that works on site and sends everything back to the office.
Your customers ask for an app
Booking, ordering, tracking a delivery, finding their documents: what your customers do today by phone or email.
Your mobile website is no longer enough
Notifications, camera, location, offline use: what a website does less well than an app.
An existing app to take over
Slow, unstable or no longer maintained: we audit it, then fix it or rebuild it.
A complete app, not just screens
User journeys and mock-ups
Screens agreed with you, and with a few users, before a line of code is written.
The iOS and Android app
Built, tried on real devices and published on the App Store and Google Play.
APIs and back office
The server, database, accounts and admin interface that keep the app running.
Maintenance
iOS and Android updates, fixes, new features: we stay responsible after launch.

Design and build
Mock-ups, then building in stages, with a version to try regularly.

Release and follow-up
Publishing to the stores, monitoring errors and user feedback, further changes.
Examples of mobile apps for a small company
The apps that serve a mid-sized business best are not social networks: they are tools.
Field app
Jobs, inspections, photos and signatures, even without signal, synced back at the office.
Customer app
Orders, appointments, tracking and documents, with notifications.
Internal app
Schedules, requests, approvals and announcements for teams who do not work at a computer.
App with AI
Photograph a document or dictate a report, and let AI fill in the fields.
Native or cross-platform app?
Two ways to build the same app. We settle it with you based on your screens, your budget and your users.
| Question | Native (Swift, Kotlin) | Cross-platform (React Native, Flutter) |
|---|---|---|
| Code | Native (Swift, Kotlin)One app per system: iOS and Android built separately. | Cross-platform (React Native, Flutter)One codebase for iOS and Android, with native parts where needed. |
| Device access | Native (Swift, Kotlin)Complete, as soon as Apple or Google release something new. | Cross-platform (React Native, Flutter)Very broad; some recent features need a native module. |
| Development effort | Native (Swift, Kotlin)Higher: two apps to build and maintain. | Cross-platform (React Native, Flutter)Usually lower: one codebase, one team. |
| When to choose it | Native (Swift, Kotlin)Demanding graphics, features closely tied to the device. | Cross-platform (React Native, Flutter)Most business and customer apps. |
What an app needs on the server side, our engineers have done at scale
At NorthStar Network, our engineers re-architected critical APIs serving 50M+ monthly users. For Slump, they built real-time dashboards fed by 5G data streams. These APIs and data flows are what keep an app fast as its number of users grows.

Questions before you launch a mobile app
How much does a mobile app cost?
It depends on the screens, the features (payments, offline use, notifications) and the tools to connect. We do not publish prices: after a first conversation, you get a free quote within 48 hours, with the scope of the first version.
Do we need an app, or is a website enough?
If your users come occasionally, a well-built website is often enough. An app makes sense for frequent use, notifications, the camera, location or offline work. We will tell you honestly.
Who publishes the app on the stores?
We prepare and submit the app to the App Store and Google Play, under your company's developer account.
Can you take over an existing app?
Yes. We start with an audit of the code and infrastructure, then propose to fix, modernize or rebuild, whichever costs least over time.
Tell us what you need.
Something to build, people to find or a question to answer. In a 30-minute call we listen and tell you honestly how we can help, and what it would take.
