iPhone measurement aid for spine teams

Cobb Angle Pro

Measure Cobb angles from spinal X-rays in a quiet, local workflow built for clinical review: manual landmarks, assisted detection, SVA marking, and exportable annotated reports.

Designed around the clinical boundary

Measurement support, not diagnostic authority.

Cobb Angle Pro helps place lines and calculate angles from spinal X-rays. It does not diagnose, recommend treatment, or replace clinical judgment. Every export keeps that reminder visible.

Workflow

Built for repeat measurement sessions.

The product language follows how clinicians talk about Cobb review: end-vertebra landmarks, observer variability, serial comparison, and clear documentation.

01

Import

Add a spinal X-ray from Photos and start an anonymized case.

02

Measure

Place Cobb points manually or review an auto-detected candidate.

03

Verify

Adjust the image, refine the landmarks, and keep clinical judgment in front.

04

Export

Generate a clean JPEG or PDF with metadata and a measurement-aid notice.

Product surface

A single-purpose workspace for X-ray review.

The app avoids general radiology clutter and keeps the measurement canvas, handles, readout, detection review, and export path in one place.

Cobb + SVA

A focused workspace for coronal Cobb angle review and sagittal vertical axis marking.

Local history

Measurement rows keep the case title, date, thumbnail, and angle easy to scan.

Assisted detection

Auto-detection is framed as a candidate to review, not an autonomous diagnosis.

Export-ready

Pro exports include the annotated image, case metadata, and a clinical-use reminder.

Screenshots

Real app screens, framed like a radiograph review desk.

Research language

Copy is intentionally careful.

Field research supported a narrow vocabulary: assist, review, verify, export. It avoids autonomous diagnosis claims and treats AI output as something clinicians inspect.
