Scolio displays your device’s tilt angle using its built-in motion sensors. Use it for everyday, non-medical angle measurements. • View continuous angle readings. • Set a zero reference and reset it when needed. • Capture a reading with a tap or a volume button. • Review captured readings during the current measurement session. Hold your device sideways with the screen upright. Readings depend on the device, its positioning, and movement. Display resolution does not establish measurement accuracy. Scolio is not intended to screen for, diagnose, monitor, or treat scoliosis or any other medical condition. Do not use its readings to make healthcare decisions.

Measure clinical angles with precision and ease. OrthoMeasure turns your iPhone into a fast, accurate digital goniometer, perfect for measuring angles on X-rays, during clinical examinations, or anywhere you need a reliable reading. Stop guessing or relying on bulky physical tools. OrthoMeasure uses your device's advanced motion sensors to calculate angles with just two simple taps. HOW IT WORKS: Align First Line: Hold your iPhone parallel to the first line (e.g., the top of the spinal curve). Tap to Set: Tap the screen to lock the first angle. Align Second Line: Hold your iPhone parallel to the second line (e.g., the bottom of the curve). Tap to Measure: Tap a final time. OrthoMeasure instantly calculates all four corresponding angles (e.g., 35°, 145°, 215°, 325°) and displays them clearly. FEATURES: High Precision: Uses your device's core motion sensors for accurate, repeatable measurements. Simple 2-Tap System: No complex buttons. Align, tap, align, and tap again. Visual Guide: See the lines you've measured drawn on the screen. Full Angle Display: Instantly get the acute, obtuse, and reflex angles for a complete picture. Clean Interface: A beautiful, dark-mode-friendly interface that stays out of your way. Designed for orthopedic surgeons, chiropractors, physiotherapists, and medical students, OrthoMeasure is the modern, simple way to get the angle you need.
