How do I test my mobility age at home?

Use the free Mobility Age web app on your phone. You take four photos of simple poses (deep squat, forward fold, overhead reach, and weight-bearing lunge), which takes about 60 seconds. AI measures the relevant joint angles and gives you your mobility age with a joint-by-joint breakdown. No equipment or app store download is needed.

Is the mobility age test free?

Yes. The assessment is completely free with no credit card required. Premium, which adds progress tracking, detailed analytics and personalised exercises, is £3.99/month or £30/year with a 7-day free trial.

Do I need to be fit or flexible to use it?

No. Mobility Age is designed for ordinary people, not just athletes or yoga practitioners. Whether you are stiff from desk work or just starting to think about your health, the test meets you where you are.

What is the difference between flexibility and mobility?

Flexibility is how far a muscle can passively stretch. Mobility is how well you can actively control a joint through its range of motion. Mobility matters more for healthy ageing and everyday function, which is why Mobility Age scores movement quality rather than stretch alone.

Mobility Age — how old does your body move?

Mobility Age is a free test that reveals how old your body moves. Take four quick photos with your phone and get your mobility age — a single number scored against peer-reviewed clinical norms. It works like the "metabolic age" on a smart scale, but for movement.

What is mobility age?

Your mobility age is the age your movement patterns most resemble, based on joint range of motion and movement quality. If you are 35 but move like a typical 45-year-old, your mobility age is 45. We measure joint angles and reach distances from four standardised poses and compare them against age-specific clinical reference data.
