App development FAQ

Answers to the most frequent questions.

How does a development project unfold? +
It all starts with a conversation to understand your needs. We then send you a technical proposal, a schedule and a detailed quote. Once approved, development starts in short cycles with intermediate deliverables you can test.
Do I receive the source code at the end? +
Yes, always. The full source code is handed over at project end. You are the sole owner of your application and can have it evolved by any developer afterwards.
Can the app be hosted at Ouioweb? +
Yes. We can deploy your application on an Ouioweb VPS and manage go-live. It's a handy option to keep development and hosting with the same partner, but you are free to host wherever you prefer.
How much does app development cost? +
Pricing depends on complexity and functional scope. A simple webapp can start at a few thousand euros, while a full mobile app with back-end is a larger budget. We provide a precise quote after analysing your needs, with no commitment.
Do you offer maintenance after delivery? +
Yes. We offer maintenance and evolution contracts to keep your application healthy over time: security updates, bug fixes, new features and technical support.
Can you help if I already have a developer? +
Absolutely. We can reinforce existing projects: code audits, architecture advice, scaling, or building specific modules alongside your in-house team.

Your project is unique, let's talk about it.
