Otter Stretch

Feeling stiff?

A few minutes a day can loosen you up, with a small otter for company.

Otter Stretch is a short daily stretching game for people who can’t touch their toes. Prop your phone, settle into a stretch you can hold, and your body steers the otter through the kelp.

  1. The standing quad's tutorial screen: a drawn figure, three how-to lines, and a diagram of where the phone goes.

    Prop the phone

    On the floor, angled up a bit, about 70° to your side and six feet away. Every stretch shows you the picture first.

  2. The setup screen: a silhouette drawn from tracking points, with a ring on each joint the camera can see. Never video.

    Get into the stretch

    It talks you through it out loud, because you’re across the room by then and often looking at the floor. It draws you as a figure, never as video.

  3. Mid-round: the otter swimming through a gap in the kelp, with the timer and gates cleared in the corner.

    Hold it

    The gap in the kelp sits at the depth you chose. Hold steady and the otter glides through. Drift, and it bumps the kelp.

It starts with what’s tight.

  • Can’t touch my toes
  • Stiff hips
  • Stiff lower back
  • Tight quads
  • Tight glutes
  • Tight inner thighs

Pick what bothers you and it builds a three-stretch routine named after it. Or pick one stretch.

It never asks you to go deeper.

Points come from how steadily you hold the spot you picked. Depth earns nothing.

Pushing past your range is how beginners get hurt, so the game doesn’t pay for it. It only makes you wobble, and wobbling is what costs you gaps.

It is also what the research says. The largest review of stretch training found that people who held a gentle stretch gained as much range as people who pushed to the point of pain.

What regular stretching does, measured.

A muscle held for about thirty seconds, a few times a day, is measurably looser within weeks, and a gentle hold gains as much as a hard one. Desk discomfort eases while you keep at it. Stretching does not prevent injury, fix posture or improve sleep.

The four findings, with their sources. None of them is a study of Otter Stretch; the app is a way to do it every day.

What you get for turning up

Ten stretches

Standing, kneeling and on the floor, each one shown and spoken before the clock starts. A session is one stretch or a routine of three, and either way it is under ten minutes.

Nothing you do here leaves the phone.

Otter Stretch follows your position with the camera. Video never leaves your phone.

No account, no sign-in, no sync, by decision. Your position is read on the phone by Apple’s own Vision framework, and your history is a file the app keeps for itself.
