Our clients


BarBrain - mobile app

BarBrain for iOS and Android provides a quick, easy and more accurate way to create inventories for bar owners. Over 400 customers are using the service including companies like Ory, Herzog, Schloss Elmau or 25hours hotel.

BarBrain uses Flutter to ship features faster and to unify the teams of developers. It also provides a consistent set of features on every platform.


BarBrain - web app

BarBrain for web complements the mobile app and gives owners and employees the ability to quickly adjust or configure the bar. The collected data can be exported as an Excel file to provide a quick overview of the inventory. Features for managing products and employees are available as well.

By using AngularDart we are able to reuse all the business logic of the mobile app. Additional costs only occurred during the development of the web UI.


We developed the iOS and Android MVP for Pump-It. With Pump-It, athletes can easily monitor their water requirements and energy balance. At the same time workouts can be planned at home and then carried out at the gym. This way the athletes always have full control over their body and results.
Many features can be adjusted individually and inject a breath of fresh air into the fitness industry.

Thanks to Flutter we were able to develop this MVP in record-time, and we could respond to customer requests dynamically during development.



We develop the MVP of the Appella app. Appella is a DSGVO-complient communication platform for music schools in Germany. It provides a messenger, video call integration, lesson management and more. Thanks to Flutter we are able to build this app for iOS, Android and Web with just one codebase.

Tapped has done a great job in supporting us with working on a large-scale multi-platform Flutter app for a big German telecommunications company. I would gladly join forces again in the future!

Frederik Schweiger

phntm, CEO

The team is very reliable and competent they did a great job and supported my fitness app project to make it great. The team does not only work strictly according to instructions but also raise concerns about some issues that could lead to problems later on, which makes my projects far more stable and better from the beginning!

Felix Mangold

M&H Production, CEO

Uncomplicated and competent cooperation convinced us of Tapped. If you need expertise in app development, you've come to the right place.

Günther Gruber

MENTZ, Head of Mobile Department

With BarBrain we support all types of gastronomy in Germany, Austria and Switzerland with a precise and cost-efficient inventory. We were looking for an IT partner who can develop a reliable app based on our designs. With the team of Tapped we have found a reliable and serious partner.
