Sit to Stand: Longevity Test

Measure your leg strength with the 30-second chair stand test — counted automatically and scored for your age. This app uses the validated 30-second chair-stand assessment — the same test physiotherapists and geriatric clinics use — and counts your repetitions automatically using your phone's motion sensors. No stopwatch, no counting, no pen and paper. HOW THE TEST WORKS • Sit in a sturdy chair, feet flat on the floor about hip-width apart • Hold the phone against your chest with both hands • Stand up and sit down as many times as you can in 30 seconds • The app counts for you and speaks encouragement as you go Your result is compared against published age and sex reference data, so you see not just a number but what it means for someone your age.
