Background

Darts Hub is a mobile companion app for darts players, designed to make scoring and gameplay easier both locally and online.

The client, Christoph, came to Olearis with a clear product vision and completed design. He already had strong product experience as a co-founder and former VP Product at PalmHR, so the concept and user experience were well defined from the start.

What he needed was an experienced engineering team that could turn the vision into a scalable production product.

Olearis joined in November 2025 and took responsibility for the engineering side of the project, including the Flutter mobile application, Firebase backend, online gameplay, and AI-powered score detection

The first production version was released in June 2026, and Olearis continues to support the product after launch.
