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.

Read full description

Cobb Angle Pro combines two focused clinical measurement workspaces: Cobb angle tools for spine X-rays and a digital goniometer for joint range of motion. For spinal images, place Cobb landmarks manually, review AI-assisted landmark suggestions, check sagittal vertical axis alignment, and organize local case records. Export annotated PDF or JPEG reports when a measurement is ready. For range of motion, measure from an existing photo, capture a new image with the camera, or use the iPhone motion sensor as a live goniometer. Set a neutral position, watch the live angle, and capture a stable reading manually or with auto capture. Built for structured measurement workflows: - Cobb angle measurement on imported spine X-rays - AI-assisted Cobb landmark suggestions for user review - SVA alignment tools and multi-curve documentation - Digital goniometer for joint range of motion - Photo, camera, and live sensor measurement modes - Shoulder, elbow, wrist, hip, knee, ankle, and spine movement records - Patient history and ROM trends by side, body part, and movement - Annotated PDF and JPEG exports Cobb Angle Pro is a measurement and documentation aid. It does not diagnose disease, recommend treatment, replace professional judgment, or provide emergency medical advice. Verify every measurement before clinical use.
