Current Projects

What we’re successfully working on right now

Apps that don’t just look great, but deliver in everyday use.

Digital is our DNA

The development of high-quality digital products is our core expertise. We have been building and marketing apps since 2009—back when the App Store was still in its early days.

Our portfolio ranges from health, fitness, and lifestyle apps to AI and membership apps, as well as applications for motivation, wellbeing, and mental health. Whether it’s a simple BMI calculator or a comprehensive weight-loss coaching app with workouts, recipes, and community features—we create digital products that connect with people and perform sustainably in the App Store and Google Play.

From the first idea to a scalable product, we support the entire process: strategy and concept development, UX/UI design, development, backend, launch, and marketing.


Winner in the fasting apps category

German App Award 2026

Our app “Intermittent Fasting for Weight Loss” was honored with the German App Award 2026—presented by ntv and the German Institute for Service Quality.

This recognition is especially meaningful to us because it is based on over 23,000 user reviews. After all, one thing matters most: our users’ satisfaction.

Technologies behind successful apps:

Collaboration at eye level

From projects grow partnerships—long-term, trust-based, and with a clear focus on quality, scalability, and impact.
