What this isn't.
social feeds
streaks or badges
AI coaches or noise
Built for people who've tried five apps and uninstalled them all. You know what to do. You just need a tool that stays out of the way.
Three things. Done well.
Cardio
Zone 2, intervals, whatever you do. Simple duration and intensity logging with heart rate trends that actually mean something.
Recovery
Sleep quality, readiness, and when to push or pull back. Data-driven suggestions, not motivational notifications.
For the long game.
You're not training for a competition next month. You're training for the next forty years. Fullstack.fit is built for people who think in decades—who care about sustainable progress, not quick wins.
If you obsess over recovery as much as output, if you've read the research on Zone 2 and strength training for longevity, if you want your tools to be as focused as you are—this is for you.
Ready when you are.
