## What is Sit to Stand?

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

BUILT FOR OLDER ADULTS
Large text, large buttons, plain words instead of icons, and one clear action per screen.

FREE
• The 30-second test with automatic counting
• Voice guidance and age-based scoring
• Sit to Stand Training, in full
• Your test history

PRO — one payment, no subscription
• Unlimited tests
• Progress charts, including your pace within a single test
• Clinic Mode — test and track several people separately
• Export to PDF and CSV for your physiotherapist or GP

PRIVACY
Everything stays on your iPhone. The app has no analytics, no advertising and no crash reporting, and makes no network connections of its own. Your results are yours.

IMPORTANT
This app is for information and self-tracking only. It is not a medical device and does not provide medical advice, diagnosis or treatment. Always consult a qualified healthcare professional. Stop if you feel unwell, and use a chair against a wall.
