About

I’m Karl, the solo developer behind Nxtstep Fitness. I built the app from the ground up to create a simple, motivating gym tracker that helps people stay consistent and make real progress. I’m passionate about fitness, product design, and building tools that people genuinely enjoy using. This is just the beginning, and I’m excited to keep improving Nxtstep Fitness based on user feedback.
