I m Micha , a solo founder from Poland and a long-time strength & calisthenics enthusiast. I ve been training consistently for almost six years, and during that time I tested a lot of fitness apps from simple workout logs to advanced coaching platforms.
What I noticed is that many apps either feel too generic or try to gamify everything, while people who train seriously often just want clarity, structure, and real progress tracking.
That s why I decided to build my own app GainTrail.
GainTrail is a workout tracking app built for people who train seriously.
Unlike most fitness apps packed with social feeds, challenges, and noise, GainTrail focuses on structured workouts and real progress. It’s designed for strength training and calisthenics, with fast logging, clear history, and a clean, distraction-free UI. This launch opens early access to users who want a simple, no-nonsense training tool and real influence on its future.
