Mobile app MVP development in Belgium

Test the idea before building the ocean liner.

Inside Web develops mobile app MVPs for iOS and Android: a first version limited to the essentials, put in front of real users to validate an idea before investing further. Scoping the features, designing the screens, cross-platform development and publication on the stores: you get concrete feedback quickly, and a codebase ready to grow.

What an MVP really is.

An MVP, for Minimum Viable Product, is not a cut-price application. It is the smallest version that genuinely solves your users' main problem, solid enough to be used day to day, and simple enough to be delivered quickly.

An MVP is not there to launch a small application. It is there to learn quickly what the big one should contain.

Most applications that fail are not badly developed. They answer a need nobody really had, or pile up features nobody uses. The MVP puts the idea in front of reality before the budget is spent.

What goes into an MVP. And what comes out.

How we build your MVP.

  1. 01

    Scoping workshop

    We clarify the problem, the users you are aiming at and the assumption to be tested. Together we decide what belongs in the MVP and what waits.

  2. 02

    User journeys and designs

    The key screens are drawn and tested before a single line of code. Changing a design costs far less than changing an application.

  3. 03

    Development in sprints

    One codebase for iOS and Android, delivered in short stages. You test each version on your own phone.

  4. 04

    Beta with real users

    Distribution to a group of testers through TestFlight on iPhone and Google Play's testing tracks, so problems are fixed before the public launch.

  5. 05

    Publication on the stores

    Listings, screenshots, privacy information and submission to the App Store and Google Play, under your own developer account.

  6. 06

    Measure and iterate

    Usage, retention, abandoned journeys, user feedback: the data decides what goes into the next version.

A technical foundation built to grow.

  • Cross-platform

    React Native and Expo: one codebase for iOS and Android, faster updates and simpler maintenance.

  • A back end that scales

    An API and a database sized for the MVP, ready to carry growth without rewriting everything.

  • Back office included

    Manage content, users and notifications without going through a developer each time.

  • Measurement built in

    Tracking of screens, key actions and retention from the very first version.

  • GDPR from the outset

    Consent, data minimisation and the privacy information the stores require.

  • Code that belongs to you

    The source code and the store accounts are yours. No hidden dependency.

Who it is for.

  • Founders and start-ups

    Test an app idea with the market before a funding round or a larger investment.

  • SMEs with an operational need

    A field tool, time recording, order taking or job tracking: validate how the team actually uses it.

  • Brands and retailers

    A loyalty scheme, a customer area or mobile ordering: check that customers genuinely take it up.

With an eye on what comes next.

A successful MVP is not thrown away: it becomes version 1. You then add what users actually ask for, a layer of AI, a connection to Odoo or to your online shop, or a complementary web platform. Every step rests on real data rather than on guesswork.

Your questions.

(Mobile app MVP)

What is a mobile app MVP?

An MVP, or minimum viable product, is the first version of an application limited to the essential features. It is dependable enough to be used by real people, so that the idea can be validated and the rest of the development guided by real data.

Why start with an MVP rather than a complete application?

Because you can never tell in advance which features users will genuinely use. An MVP lets you check the market's interest quickly, limit the initial investment and build what follows on what works.

How long does an MVP take to develop?

A well-scoped MVP usually takes a few months, from scoping to publication. The timing depends on the number of screens, the features chosen and the integrations required. The schedule is set after the scoping workshop.

Is an MVP a lower-quality application?

No. An MVP has fewer features, not less quality. The interface has to be polished and the application dependable, otherwise user feedback will be about the flaws rather than about the idea.

Will the MVP be available on iPhone and Android?

Yes. Inside Web develops cross-platform with React Native and Expo: one codebase produces an application for iOS and one for Android, published on the App Store and Google Play.

Can the MVP grow into a complete application?

Yes, that is the point. The architecture is designed to grow from the start: the MVP becomes version 1, and new features are added without starting over.

How do we test the application before the public launch?

Through TestFlight for iPhone and Google Play's testing tracks for Android. A group of testers installs the application, uses it in real conditions and reports problems before the official release.

Do we need an Apple and Google developer account?

Yes. The application is published under your own developer account, so that it remains yours. For Google Play an organisation account is advisable: some recent personal accounts have to run a closed test before they are allowed to publish.

Who owns the application's code?

You do. The source code, the store accounts and the data are yours. You remain free to develop the application further with Inside Web or with another team.

How do we know whether the MVP has succeeded?

By setting measurable indicators at the outset: active users, retention after a few weeks, completion of the main action, and qualitative feedback. That data decides what comes next.

Could a progressive web app serve as an MVP?

Sometimes, yes. A PWA lets you test a use case without going through the stores. But if the experience relies on notifications, offline use, the camera or a presence in the stores, a native cross-platform application gives more representative results.

Is the MVP GDPR-compliant?

It has to be from the very first version. Consent, data minimisation, a privacy policy and the declarations required by the App Store and Google Play are part of the development, not added afterwards.
