Adjusted after each session

Most apps give you the same program as everyone else. Loosen changes the next session based on what you marked as tight, how much you sat, and how you slept. Small adjustments, not a new routine every day.

No manual logging

Your phone already tracks your sleep and workouts. Loosen reads from there, plus what you said was tight last session. You don’t enter anything by hand.

You’re not getting older. You’re getting tighter

Ten minutes a day is the difference between 32 feeling 32 and 32 feeling 60.

The goal is simple: less stiff in 30 days

I’ve spent most of my life at a desk.

By the time I noticed my hips, they were locked. I went looking. Research papers, physiotherapist videos, half the App Store. Everything asked me to pick what to do. Nothing read my body, my data, or what I’d done that day. I wanted a sidekick that knew the next best stretch for me.

Whoop scored my recovery. Oura scored my readiness. Why didn’t anything score my flexibility?

I built it for myself first.
