Apps

Web and mobile app development, on iPhone, Android and the browser

Your app in the hands of your first users within a few weeks, then on the App Store and Google Play once usage is proven. A single app for the browser, iPhone and Android, which belongs to you.

The market in figures

What public statistics, research and industry studies measure. Each figure links to its source, and when the author sells consulting or AI, we say so.

What you gain

Users before the stores

Your app first runs in the browser and installs on the home screen. You test it with real users while the rest is being built.

Three platforms for the price of one

Web, iPhone and Android share the same code. You do not pay two teams, and a fix made once lands everywhere.

Fixes in a few minutes

Interface tweaks ship without a new store review. Your users are not left stuck on a bug for days.

A release with no nasty surprise

The common reasons for store rejection are handled at design time, not discovered at submission.

Reliable data

What must be right, such as a counter, a date or an access right, is computed by the server. Nobody cheats by changing the time on their phone.

Your app belongs to you

The code, the database and the developer accounts are in your name. You can take everything in-house or change provider without rebuilding anything.

Who it is for

  • You want a tailored tool for your customers or your teams, and off-the-shelf software imposes its own way of working.
  • You want to put a first version in the hands of real users before investing in everything else.
  • Your business runs on a shared spreadsheet and WhatsApp messages, and you need a real app on everyone’s phone.

What you receive

  • Written scoping: what the app does on day one, and what will wait.
  • Your app on the browser, iPhone and Android.
  • A version that installs on the home screen within the first weeks.
  • Publication on the App Store and Google Play under your account, listings and screenshots included.
  • Regular updates and a release log your users can read.
  • The documentation to run the app.

How it goes

  1. Scoping

    You decide with us what the app must do on day one.

  2. First version live

    Your first users use it in the browser, and their feedback sets the priorities.

  3. Iterations

    You receive short releases, each one checked and published.

  4. Store release

    Your app reaches the App Store and Google Play, and we handle the review.

Frequently asked questions

What if we do not yet know exactly what the app should do?

That is what scoping is for, and it always starts with an inventory: how your teams work today, with which tools and which workarounds. If off-the-shelf software or an automation of your current tools solves the problem, we tell you before writing a single line of code.

Do we need the stores from day one?

No, and it is often a mistake. The installable web version puts the app in your users’ hands within a few weeks; the stores come once usage is proven, with the same code.

Why a developer account in your company’s name?

Because the app belongs to you, and because an organisation account avoids the closed testing phase that Google Play requires of recent personal accounts before production. We help you open it.

What if the app must change after delivery?

Interface tweaks ship in a few minutes, without a new store review. Deeper changes go through a new version, which we plan with you.

Why a single app rather than two native apps?

Because a company should not have to pay two teams for two codebases that do the same thing. With React Native and Expo, your app keeps access to the phone’s features: notifications, camera, location.

What if the app uses AI: what does it cost to run?

We price it at scoping, then we reduce it by combining models: sorting or summarising goes to a small model, the most powerful one only steps in where it adds something, and a cache avoids paying twice for the same answer. On Palmora Property, moving translation to an AI model divided its cost by 60, and 95% of segments come from the cache without calling the AI again. That ratio holds for that site, not necessarily for yours.

Do you use AI to build the app?

Yes, under control. Agents write the code in a loop: they propose a change, run the checks, read what fails and fix it until everything passes, within a limit set in advance. Each version is then reviewed and approved by a person before it is published: AI speeds up the writing, the decision stays human.

Rarely just one service. Most of our clients combine several: build your cart and ask for a bundled quote, a set of services gets a better price.

Cyber Resilience Act: report a flaw within 24 hours

Since 11 September 2026, makers of software or connected devices sold in Europe must report exploited vulnerabilities and severe incidents within 24 hours. Who is covered, what must be reported, and what this obligation brings to a business that commissions or buys applications.

Are AI companions dangerous for teenagers?

An American survey indicates that most teenagers have already talked to an AI companion, but its figures come from a campaigning non-profit and call for caution. The design question, though, is a legitimate one, and Europe has already answered it in part.

Agentic AI: how an agent's loop works

An AI agent does not do everything in one go: it runs in a loop, gathers context, acts, checks and starts again. Understanding that loop means knowing where to put the controls, the limits and the human review.
