Clinical-grade scoliosis screening, right from your phone
The Scoliometer App measures the angle of trunk rotation (ATR) — the established metric of the Adam’s forward-bend test — turning any smartphone into a validated screening tool for clinics and homes alike.
What the app does
Everything you need to screen for scoliosis quickly and reliably.
Accurate ATR measurement
Measures the angle of trunk rotation, the established metric used in the Adam’s forward-bend screening test worldwide.
Extended 0–50° range
The digital design screens curves up to 50° — beyond the ~30° limit of a physical scoliometer — suiting mild to severe cases.
Simple four-step guide
A guided, four-step process walks parents and professionals alike through taking a reliable reading.
Fast, clean, accurate
A lightweight, distraction-free interface optimised for the latest smartphones.
50 languages
English, Spanish, French, German, Simplified & Traditional Chinese, Portuguese (PT & BR), Japanese, Korean, Thai, Vietnamese, Swedish, Finnish, Greek, Italian and Indonesian.
For clinics & home
Built for medical professionals screening patients and for families monitoring at home.
Research-backed method
Smartphone-based scoliometer screening has been validated in peer-reviewed research (European Spine Journal, 2022).
Affordable & always available
A convenient, low-cost complement to in-clinic screening — ready whenever you need it.
How it works
Four steps to a reliable reading.
Bend forward
The person being screened bends forward at the hips with arms hanging relaxed — the Adam’s forward-bend position.
Place the phone
Rest the phone gently across the upper back, perpendicular to the spine at the most prominent point of the curve.
Read the angle
The app instantly displays the angle of trunk rotation (ATR) on screen.
Act on the result
If the reading is raised, schedule an assessment with a qualified healthcare professional.
