A startup’s first product
A reduced version, live on the stores, to measure real use before investing in the rest.

Mobile app development in Lille
We build iOS and Android apps for startups and small companies around Lille, from mock-up to release. One codebase for both platforms: that is what keeps the budget reasonable.
Common features
The apps we build from Lille
The Lille area has many startups, especially around EuraTechnologies, and a lot of retail and logistics companies. The first need a testable version quickly. The second need a reliable tool for teams in the field.
App for field teams
Data entry, photos, offline access, then sync when the network is back.
Notifications and reminders
Messages sent at the right moment to bring the user back, without flooding them.
In-app payments
In-app purchases or subscriptions that follow Apple and Google rules, tested before submission.
Scoping possible in Lille
We can run scoping workshops in Lille, with the people who will use the app. Watching a technician or a customer use it for real changes more decisions than a long specification meeting.
Method
- 01
Scoping
We define users, frequent actions and the version really worth launching.
- 02
Journeys and mock-ups
Each screen is designed to make the main actions obvious on a phone.
- 03
Build and tests
We test accounts, payments, notifications and error cases on real devices.
- 04
Release and follow-up
We prepare the stores, follow review and plan the next versions.
An app is not always the answer
If customers check on you once a year, a good website costs less and is enough. An app makes sense when people come back every week.
Delivered anywhere in France
The first meeting can be in person. Tests, intermediate builds and the release then run well remotely.
Frequently asked questions
Building a mobile app in Lille
Do I need to be in Lille to work with you?
No. We can meet in Lille for scoping, then follow the project remotely with test builds installed on your phones.
What budget for a first version?
Plan on €10,000 and up. The exact amount is set after scoping, based on screens, user accounts and services to connect. We always propose a reduced first version to test before going further.
Why React Native?
One codebase produces both the iOS and Android apps. For most projects users see no difference, and you avoid paying for two builds.
Can the app work offline?
Yes for reading and data entry, if planned from the start. Data syncs when the connection returns. That choice has a cost, which we quote separately.

Describe the use, we will price the first version.
Who opens the app, to do what, and how often. Those three answers are enough to know whether the project holds up.
