Frequently asked questions
Is it better to build native or cross-platform?
It depends on the project. Native (Swift/Kotlin) is unbeatable for performance and full access to platform APIs. Cross-platform (React Native / Flutter) cuts costs roughly in half and speeds up time to market. We'll advise you based on your constraints.
How much does a mobile app cost?
Cost depends heavily on functional scope, native vs. cross-platform choice, required backend integrations, and the number of platforms targeted (iOS, Android, or both). Rather than give unreliable ranges, we prefer to provide a precise, itemized quote after scoping your project. Describe your project through the form — we reply within 24h.
How long does it take to develop an app?
Plan for 3 to 4 months for a functional V1, sometimes 6 months or more for ambitious projects. We can deliver an MVP in 6 to 8 weeks to validate the concept quickly.
Do you handle publishing to the app stores?
Yes, entirely. We set up Apple ($99/year) and Google Play ($25 one-time) developer accounts, prepare store assets, submit the app, manage any rejections, and handle publication.
What happens after launch?
Corrective maintenance (bug fixes), evolutive maintenance (new features), Apple and Google SDK updates, and store review monitoring. Monthly plan or ticket-based, depending on your needs.
Can you take over an existing app?
Yes. We regularly take over projects already in progress, whether it's auditing an existing app, fixing critical bugs, or adding major new features.
