Hi, I’m Dieter, and I created Dartcounter (Dartcounterapp.com). My motivation wasn’t being a darts expert – quite the opposite! When I first started playing, I loved the game but found keeping accurate scores and tracking stats difficult and distracting.
I figured I couldn’t be the only one struggling with this. So, I decided to build a solution: an easy-to-use application that everyone, no matter their experience level, could use to manage scoring effortlessly.
My goal for Dartcounter was simple: let the app handle the numbers – the scoring, the averages, the stats, even checkout suggestions – so players could focus purely on their throw and enjoying the game. It began as a way to solve my own beginner’s problem, and I’m thrilled it has grown into a helpful tool for the wider darts community.
