Yoga Pose Checker: AI webcam scoring against reference poses

Practising yoga at home with no one to correct you? Pick a pose and step in front of the camera. The AI compares your arm, hip and knee angles with the reference, tells you things like “bend your left knee more” and starts a hold timer once your score reaches 80.

How to use the Yoga Pose Checker

  1. Choose a pose, or choose “Auto detect” to let the AI work out which pose you are in.
  2. Start the camera and step back until your whole body is visible (side-on or facing, as the reference suggests).
  3. Match the reference figure and follow the cue for your lowest-scoring joint.
  4. At a score of 80 or more the hold timer runs; reach your goal, then move on to the next pose.

How is the score calculated?

Each pose has reference angles for both elbows, shoulders (upper arm to torso), hips and knees. The AI measures the same angles on your body and compares them one by one: within tolerance earns full marks, larger deviations lose more. The weighted average is your score. Poses are mirror-aware, so either leg can lead.

Which poses are supported?

Ten foundational poses: Mountain, Tree, Warrior I, Warrior II, Triangle, Chair, Downward Dog, Plank, Goddess and Star. They are standing or easy to film from the side or front; floor twists and inversions with heavy self-occlusion are not supported yet.

My score is low but I think my pose is right

Reference angles follow a common teaching version, and styles differ. Camera angle, loose clothing or body parts out of frame also skew angles. Try the relaxed setting and place the camera in the suggested direction.

Safety

Practise within your limits and never force a stretch into pain for a score. During pregnancy, or with high blood pressure, glaucoma or joint injuries, some poses (such as head-below-heart poses like Downward Dog) need guidance from a qualified teacher.

Frequently asked questions

Do I need yoga experience?

No. The reference figure shows the target and cues tell you what to adjust, which suits beginners learning the basics.

What does auto detect do?

It compares your pose with every pose in the library and shows the closest match and its score, handy for free practice.

Can I use it on a phone?

Yes. Lay the phone sideways on the floor or a stand 2–3 m from the mat with your whole body in view.

How long should I hold each pose?

Beginners can hold for 15–30 seconds with 3–5 deep breaths, lengthening holds as you progress.

Is any data saved?

Video is never saved or uploaded. Only results such as your best hold time are stored in this browser.
