SagittalMeter Lite
This application assists medical practitioners in measuring crucial sagittal balance parameters directly from sagittal X-rays. It helps analyze spine problems and pre-operative planning by calculating pelvic incidence, pelvic tilt, and sacral slope.
- Measure sagittal balance parameters
- Directly use phone on X-rays
- Calculate Pelvic Incidence (PI)
- Calculate Pelvic Tilt (PT)
- Calculate Sacral Slope (SS)
- Aid in spine problem analysis

SagittalMeter is an educative app to easily measure sagittal balance parameters, by directly placing your phone on the sagittal X-Rays. The sagittal balance is an imperative factor to take into consideration for all practitioners treating spine problems and particularly for surgeons during the pre-operative phase. The compensatory mechanisms of a sagittal unbalanced spine may prevent a successful surgery outcome. A fundamental understanding of a correct sagittal alignment is strongly recommended in determining the correct use of fusion or non fusion devices. SagittalMeter enables you to measure 3 fundamental angles which are essential to analyze sagittal alignment: • Pelvic incidence (PI) • Pelvic tilt (PT) • Sacral slope (SS)
Cobb Angle Pro Spine X
This app provides clinical measurement tools for spine X-rays and joint range of motion. It offers AI-assisted landmark suggestions for spine measurements and multiple modes for capturing joint angles from photos or live sensor data. Users can organize case records and export annotated reports.

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.
