Loosen: Flexibility Coach

YOU MEANT TO STRETCH YESTERDAY. AND THE DAY BEFORE.
Loosen makes it the easiest 10 minutes of your day, and tells you exactly which stretches your body actually needs.

FLEXIBILITY SCORE
Your daily anchor: a single number, 0–100, calculated from your Apple Health signals (sleep, sit time, HRV, recent workouts), the per-area baseline you set in the 30-second flexibility quiz, and how long each muscle group has gone untouched.

It updates after every session and when you open the app.

TODAY'S PICK
A short routine prescribed straight from your score, with the reasoning shown.
“You sat 11 hours yesterday. Hips first.”
No black box. Two taps after each session tell us how it felt and where you're still tight, and the next session adjusts quietly.

A PLAN THAT'S ACTUALLY YOURS
No fixed program, no off-the-shelf template.
Your plan is built around your goals, your problem areas, your sleep, your sit time, your training load, and how you felt after the last session. The next session is built for the body you have today, not the next slot in a fixed program.

A LIBRARY THAT GOES WHERE YOU'RE TIGHT
190 guided routines, indexed by what's bothering you:

• Tight hips after long sitting
• Lower-back relief
• Shoulders and neck
• Pre-bed wind-down
• Post-run lower-body
• Hamstrings
• Splits work

Or describe what you need (“10 minutes for a stiff lower back, evening”) and the AI Routine Builder assembles a session from the pose library.

BUILT FOR THE BODY THAT SITS ALL DAY
Loosen is for the person who works at a desk, knows they should stretch, and wants useful signal over wellness vibes.
Honest measurements, no flow language, no streak shame. The numbers do the talking.
