Solution

Customer apps connected to your existing systems

An app is the most direct channel to your customers. For it to do more than the website, it needs access to customer accounts, orders, content and payments. We develop apps for iOS and Android as well as progressive web apps, and take over existing apps when the previous provider is no longer available.

Starting point

A connected app offers your customers real added value

Many apps were built as standalone projects and then only patchily maintained. Without integration with the back end and CRM, the app shows less than the website, and customers switch back to the browser.

With every new version of iOS and Android, the maintenance effort increases. Without clear responsibility for operation, the app loses ratings and users.

Typical signs

  1. The app was built by a service provider who is no longer available.
  2. New iOS and Android versions regularly cause errors.
  3. Website, app and portal access different versions of the data.
  4. Login, payments or notifications do not work reliably.

Scope of services

From the app to the back end, everything comes from a single source

  • Native apps for iOS and Android

    For functions that make full use of the device: camera, location, notifications.

  • Flutter and progressive web apps

    One codebase for several platforms, or an app that bypasses the App Store.

  • Mobile design and UX

    User guidance that works on a small screen, tested on real devices.

  • Integration with backend, CRM and payment

    Via REST APIs, with the same data as the portal and shop.

  • Multichannel platforms

    Web, mobile and smart TV from a shared back end.

  • App takeover and maintenance

    Code audit, store updates, adaptation to new operating system versions and further development.

Approach

From the first conversation to operation in four steps

  1. Analysis

    We clarify target groups, functions and the systems from which the app draws its data.

  2. Architecture

    We decide between native, Flutter and PWA and define the interfaces.

  3. Implementation

    Design, development and testing on real devices through to publication in the stores.

  4. Operation

    Updates for new operating system versions, monitoring and further development.

2channels on one platform: self-service portal and app, connected to SAP and Dynamics

  1. Problem

    The customer portal was based on a legacy PHP application that could hardly be extended any more. Self-service for web and app was required.

  2. Solution

    Java microservices on Azure with Kubernetes replace the legacy application and connect SAP and Microsoft Dynamics. Content comes from Adobe Experience Manager.

FAQ

Frequently asked questions

Native apps get the most out of the device, Flutter saves effort across two platforms, and a progressive web app works without an app store. We recommend the route based on scope of functions, target group and budget, and explain our reasoning.

Yes. We start with a code audit, review the architecture, dependencies and store access, and draw up a maintenance plan. We then take over updates and further development.

Via REST APIs to your back end, CRM or ERP. Where an interface is missing, we develop it, often together with the portal or shop, so that all channels use the same data.

We take care of this as part of a maintenance contract. This includes adaptations to new operating system versions, security updates and maintaining the store listings.

Yes. The REEA Group has developed a streaming platform for web, mobile and smart TV that runs in three world regions with several payment providers.
