Build an iPhone and Android mobile app

An application ready for Google Play and the App Store — custom-designed and built by the studio in React Native — with what it takes to be genuinely useful: notifications, payments, offline mode, updates without going back through the stores.

What the project includes

One code base, iPhone and Android

Both from the same product: less cost, less delay, and a single version to maintain.

The features that matter

Accounts and roles, notifications, payments and subscriptions, messaging, audio and video calls, scheduling, translation — according to what your business needs.

Publication included

Listing, screenshots, privacy policy, content rating, submission: you do not have to learn the Play Console.

Remote updates

Fixes and improvements reach your users without a new store review, whenever possible.

How we work

  1. Framing — your goals, your users, your constraints, your calendar — written together.
  2. Design — identity, components, mock-ups of every screen: you see the product before it exists.
  3. Development — in delivered, testable stages, never as a black box.
  4. Publication and follow-up — going live, stores, real payments, data protection — then monitoring and evolutions.

Built on a foundation that already runs

Two platforms designed and published by the studio, in production with real users:

Orion UniversePersonal development universe: daily content, subscription pillars, guided paths, multilingual, online payments. SerenaMobile app and installable web app, schedules, presence, moderated reviews, notifications.

Frequently asked questions

How much does a mobile app cost?

A mobile application starts from €30,000: accounts, business logic, notifications, several languages. As soon as there are accounts on both sides, online payment and a commission, it is a platform, from €100,000. Every project is priced after a study, on its real scope.

How long does it take?

An application is built over several months, in delivered and testable stages; the schedule is written with you at the framing stage, and kept.

Do I need an app, or is a website enough?

Often, an installable web app is enough and costs less. We will tell you frankly at the framing stage: a native app is justified when you need reliable notifications, offline mode, or presence on the stores.

Who handles store publication?

The studio. Developer account, listing, screenshots, privacy policy, submission and review follow-up are part of the project — on Google Play first, on Apple's App Store if the project requires it.
