Sit to Stand: Longevity Test

Measure your leg strength in 30 seconds, train between tests, and watch the number move.

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.

NEW — SIT TO STAND TRAINING
Testing tells you where you stand. Training moves the number.
• Short guided sessions of sit-to-stand sets, built around your last result
• Voice coaching through every set, with rest between them
• Choose your own training days and get one gentle reminder — never daily
• Always free

THE RETEST LOOP
• Set your own cadence — every one to four weeks
• One reminder when your next check-in is due
• See the change since last time, and your count over months
