App Development

Not another app agency, but a full-service provider of software solutions

For Quality Leaders

We specialize in highly complex apps that are business-critical or hardware-related and have to meet comprehensive security requirements. This sets us apart from classic app agencies, whose origins often lie in advertising or purely online business. For example, we implemented mobile payment for one of the world's largest retailers - back in 2015.

The integration of modern frameworks such as Google Flutter allows us to economically implement your application purpose, even across multiple platforms.

Hardware Specific App

Whether Wi-Fi onboarding or full control of your product through an app: We master the interfaces between smartphone and the outside world. Both under iOS and Android, we are at your side as early as the conception stage.

Thanks to our experience, we can offer you readymade solution modules for smooth communication via Bluetooth®1 Low Energy. But also the integration of complex Bluetooth® EDR (also called Bluetooth® Classic) products, with all possibly necessary certifications, do not pose any problems for us.

Our hardware and firmware development services provide you with specialists who not only have the equipment, but also the experience to get to the bottom of even the most complicated compatibility issues.

Comprehensive Services

At grandcentrix conceptors, designers, usability experts, software developers, solution architects, testers and project managers work under one roof. We develop your solution with our own team members who work for us full-time. Optionally, we supplement our services from our proven partner network. We steer your solution through all phases of the project cycle. Starting with ideation and user experience design, through the implementation of frontends and backend, to ongoing operations and connected maintenance.

Our Strengths

IoT Device Onboarding

IoT Device Onboarding

Not every IoT device available in the field can rely on Bluetooth® to provide initial provisioning, if necessary. Whether it's Wi-Fi access data, settings, firmware updates, or simply linking a device to a location, we'll work together to find a solution.

Bluetooth® Connectivity

Bluetooth® Connectivity

Through many years of experience with Bluetooth® across all platforms and many different manufacturers, we can support you quickly and competently in conception, development and testing. In doing so, we can draw on an extensive repertoire of solution modules.

Platforms & Assistants

Platforms & Assistants

We have already completed many projects together with certifications for the most popular smart home platforms. We regularly integrate Siri, Alexa and other voice assistants. In 2020, for example, we developed the "Interior Push Button WLAN" for Hörmann, which connects the Hörmann garage door to Apple HomeKit.

Modern Development

Modern Development

The modular architecture of our solutions allows components once written in Kotlin Native to be used on iOS and Android. This is particularly suitable for building blocks that communicate with third party systems or hardware. This reduces development and QA efforts and ensures a good user experience regardless of the operating system. We also have a lot of experience with cross-platform frameworks and will find the right approach for your project.

Backends & Integrations

Backends & Integrations

Very few apps are able to operate without platforms to communicate with. Apps often take over the function of the primary frontend of an application and must be integrated into both existing and new backends. Therefore, a holistic view of the system architecture is mandatory. As an end-to-end service provider, classic integration tasks are also a predictable challenge for us.

Enterprise Level

Enterprise Level

App productions follow the principles of classic software development projects. We develop based on a proven agile process model that has matured over many years. The essential feature is a highly iterative approach that thrives with your constant feedback. Of course, a dedicated project manager is available to you at all times throughout the project phase.

Tracking & Analytics

Tracking & Analytics

We make sure that your app is ready for standard tracking solutions and are also happy to advise you when choosing a suitable provider. We support the creation of a purposeful tracking concept that enables you to learn more about your users. By continuously analyzing user behavior, you can draw and derive conclusions more easily towards decision makers and thus secure future budgets for further developments.
