Case Study 03 - Flutter · iOS & Android

From a rejected iOS app to a sellable, dual-platform product.

Mi Box Live had spent more than £30,000 over eighteen months on an iOS-only Unreal Engine app, only for it to be rejected by the App Store. Resolve Beyond did not simply rebuild it. We challenged the original direction, recognised that an iOS-only product would not work for many schools, and moved Mi Box Live onto Flutter so it could reach both iOS and Android users. Six weeks later, the app was live on both stores with a commercial route forward.

The situation

The app had been built for the wrong platform from the start.

Mi Box Live is an educational app designed for children in schools. The client had already invested more than £30,000 over eighteen months in an Unreal Engine build aimed only at iOS. When the app was submitted, it was rejected by the App Store and the original agency walked away.

The rejection was only part of the problem. Once we understood how the product would actually be used, it became clear that the original platform decision was wrong for the market. Many schools rely on affordable Android tablets rather than iPads, so an iOS-only app immediately excluded a large part of the intended audience.

Resolve Beyond did not just rebuild the app. We challenged the direction of the product, preserved the valuable parts of the original investment and moved Mi Box Live onto a platform that could support both iOS and Android, giving it a genuine route into the schools market.

Services delivered
Unreal Engine build rejected by the App Store for lack of usability
Original platform direction excluded many schools using Android tablets
Original agency left with no handover and no intention to continue
Missing the animations, sound and interactivity children need
Other agencies quoted £50,000+ and fifteen months for a full rebuild
£30,000+ already spent with nothing usable to show
We'd spent over thirty thousand pounds and eighteen months and had nothing we could put in front of a school. Every other agency told us we needed to start again. Resolve Beyond looked at what we already had, kept the foundations, and rebuilt it in Flutter in six weeks. We're on both stores, the kids love the animations, and we now have a subscription model to sell it worldwide.

The full timeline

What happened, and when.

From a rejected app with no clear route to market to a live, dual-platform product with subscriptions, store approval and a commercial model behind it.

Before Resolve Beyond
£30k spent, App Store rejection, agency gone
Eighteen months and £30,000+ on an iOS-only Unreal Engine build. Rejected by the App Store. The agency walks away. Others quote £50k+ and 15 months to start over.
Assessment
Challenge the original direction, preserve what still has value
Rather than blindly recreating the same iOS-only product, we review the market, question the platform choice and identify the databases, structure and data architecture worth carrying forward.
Rebuild in Flutter
Repositioned as a product for both iOS and Android
The app is rebuilt in Flutter on the valuable parts of the existing foundation, opening it up to Android-based schools as well as iOS users and giving the product a far wider addressable market.
Six weeks — Launched
Both stores live, with the interactivity children need
Animations, sound and interactivity are built in. Both iOS and Android versions are published within six weeks.
After launch — Growth
Subscriptions, new markets and continued product development
The subscription model creates a route to revenue through both stores. Since launch, we have continued supporting updates, testing and feature development as Mi Box Live moves into growth, including preparation for new markets following the client's recent exhibition in America.

The bigger decision

We did not just rebuild the app. We changed its direction.

Resolve Beyond recognised that recreating the same iOS-only product would not solve the real problem. The app needed to work for the schools market, which meant reaching Android users as well as iOS users.

By preserving the valuable parts of the original investment, rebuilding the experience in Flutter and adding the subscription model needed to sell through both app stores, we helped turn a stalled project into a commercial product with a future.

A product with a route to market

Resolve Beyond did not just rescue Mi Box Live. We took a rejected, iOS-only app with no clear route to market and turned it into a live, sellable product for iOS, Android and the schools market.

After the fix

From rescue into growth.

Since launch, Resolve Beyond has continued to support Mi Box Live as it moves beyond rescue and into growth.

With the client recently exhibiting in America, the app is now being taken to new markets, supported by ongoing updates, testing, subscription improvements and feature development that keep the product ready to sell, scale and evolve.

Ongoing partnership includes
Feature development across iOS and Android
Subscription improvements and in-app commerce
App Store and Google Play release management
Ongoing testing and updates for new markets
Named team supporting the product as it scales
