Who it’s for
The Codex guide
01A successful app solves a precise problem better than what already exists. We start by defining your users’ main journey and the few features that will bring them back every day, before thinking about the rest.
02We then design the screens and test them on real phones before development. With Flutter or React Native, a single codebase powers iOS and Android, which shortens timelines and reduces maintenance costs.
03Release is only the beginning. Usage statistics, user feedback and store ratings guide the next versions. We stay at your side to evolve the app and keep it compatible with new system versions.

Method
A clear framework, sign-off at every step and a single point of contact from the first workshop to maintenance.
A workshop to understand your business, your users and your constraints. You leave with a clear scope, a schedule and a detailed quote.
User journeys, mock-ups and technical architecture. You approve every screen before a single line of code is written.
Short sprints, a demo at every step and permanent access to progress. The code is tested, documented and yours.
Go-live, training for your teams, then maintenance and new features. We remain your technical team after delivery.
For most projects, Flutter or React Native deliver iOS and Android from a single codebase, faster and at lower cost. We recommend native only if your product requires it.
Yes, we prepare the listings and screenshots and handle the review process with Apple and Google.
The cost depends on the number of screens, the features and the back end required. We send you a detailed quote after a first conversation.
