Why I'm building this

Hey, I'm Søren—a runner, former triathlete, and developer from Denmark with a background in sports science. I built Trainna because I was tired of paying for features that should be free.

Most training apps lock basic stuff behind paywalls. Want to create a workout? Premium. Seeing your personal records? Premium. Planning your training calendar? You guessed it. These features cost almost nothing to provide, but they charge anyway.

I also couldn't stand how slow most training apps are. Waiting seconds for screens to load, laggy scrolling, endless spinners—it's 2026, this shouldn't be the norm. Speed is a core focus of Trainna. Everything should feel instant.

I wanted an app that gives you everything you actually need for free, with an optional Supporter tier for people who want to help fund ongoing development.

Most apps make you choose between social features, planning, analytics, and recovery context. Trainna has it all in one place: social features, flexible training plans, detailed analytics, and recovery tools. One app, everything you need.

Plans aren't rigid. Need to skip a day? Easy. Want to edit a workout? Done in seconds. Your training can adapt to your life, not the other way around. Flexible down to the minute.

So that's Trainna. Unlimited syncing, full analytics, workout planning, personal records—all free, forever. No credit card tricks, no 7-day trials that auto-charge you. The Supporter tier exists to keep development going, not to gatekeep basic functionality.

I'm building the training app I wish existed. Hope you like it.
