What we do
Before developing anything, we check together that an app really is the right answer: for many projects, a progressive web app costs three times less for an equivalent result. When an app is justified, we first design the main user journeys, then develop on a cross-platform base.
-
1
Scoping mobile use cases
We identify the features that genuinely require an app and those that can stay on the web.
-
2
User journey and screen design
Interactive mock-ups that follow iOS and Android conventions, approved before development.
-
3
Cross-platform development
A single codebase for both platforms, with the specific adjustments each one needs.
-
4
Testing on real devices
The app is tested on several models and screen sizes, not just in an emulator.
-
5
Publication on the stores
We prepare the listings, visuals and compliance, then support the submission through to approval.

Why choose us
Honest advice from the outset
If a mobile app is not justified for your project, we will tell you and suggest the right alternative.
Two platforms, one development
Cross-platform greatly reduces the initial cost and the maintenance compared with two native apps.
Publication handled for you
Developer accounts, store listings, screenshots and compliance: we handle the whole process from start to finish.
Tested on real devices
Emulators hide many flaws. We test on real phones, both old and new.

Service FAQ
Yes. The Apple account costs €99 a year and the Google Play account a one-off €25. They must be in your name so that you remain the owner of the app.
Allow 24 to 72 hours for Google and 1 to 7 days for Apple, provided the listing is compliant. We prepare the submission to limit back-and-forth.
For the vast majority of management, booking or content apps, users see no difference. Native development remains relevant for very demanding uses such as gaming or augmented reality.
It can, and this is included in the Pro and Custom packages: viewed data is cached and synchronised when the network returns.
Allow for a monthly contract from €129: iOS and Android change every year, and an app that is not maintained eventually gets removed from the stores.
