Your plan, rebuilt every night.

Most apps give you a program written for everyone. Loosen rebuilds yours every night around your actual day: your sleep, your sitting, your last session. Open it tomorrow and it just fits.

Loosen app — today's plan

Nothing to log.

Apple Health already has your sleep, sitting time, and workouts. Loosen reads all of it. Nothing to log, nothing to configure, nothing to remember.

Not yoga. Not a stretching library. Not rehab.

For the desk worker who feels stiff. Most stretch apps hand you a library. We hand you the next eight minutes.

Built on physiotherapy.
After 30 days, you feel less stiff.

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?

So I built it.
