Built for clinical review

A focused iPhone workspace for spine teams who need measurements, export notes, and local case history. Each Cobb angle is calculated from 4 landmark points and shown to 0.1°.

How It Works

Designed around the clinical boundary. Measurement support, not diagnostic authority. 4 steps take a case from X-ray import to annotated export.

01. Import

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

02. Measure

Place 4 Cobb points manually or review an auto-detected candidate.

03. Verify

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

04. Export

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

Keep measurement review organized.

Patient folders, thumbnails, dates, and angle rows stay easy to scan.

Few Awesome Features

A focused workspace for 2 measurements: coronal Cobb angle review and sagittal vertical axis marking.

CASE WORKSPACE

Make review easier
without leaving the device

Keep imported X-rays, thumbnails, dates, and measurement rows in one local workflow. Saved angle rows show each measurement to 0.1°.

  • Cobb and SVA measurement surfaces
  • Patient folders with local history
  • Quick remeasure path for saved cases
  • Angle summaries built for scanning
ASSISTED REVIEW

Candidate detection, clinician verified

Assisted detection is framed as a candidate to review, not an autonomous diagnosis. Each candidate shows its Cobb angle to 0.1° so you can check it before saving.

Designed for Measurement Review

Cobb Angle Pro helps clinicians measure Cobb angles on iPhone with local X-ray review, assisted landmark checks, SVA support, and PDF exports.

REVIEW LANGUAGE

Assist. Review. Verify. Export.

The app avoids autonomous diagnosis claims and treats assisted output as something clinicians inspect. Every final measurement remains user-reviewed before it is saved or shared.

Simple, Transparent Workflow.
Start with Cobb Angle Pro.

Choose one of 3 measurement paths that fits the case in front of you.

01

Manual Cobb review

Place superior and inferior end-vertebra landmarks, then verify the live angle readout before saving.

02

Assisted candidate check

Use auto-detected landmarks as a candidate input, then refine placement with manual control.

03

SVA and export

Mark sagittal alignment context and export an annotated JPEG or PDF with case metadata.

Range of Motion Measurement Guides

18 movement-by-movement protocols for recording joint and spine range of motion with a digital inclinometer workflow; 4 of them have a guided protocol in the app.

Frequently Asked Questions

Is this a diagnostic tool?

No. Cobb Angle Pro is a measurement aid. It assists with X-ray measurement workflows but does not diagnose disease or replace clinician judgment.

Where is my data stored?

Imported X-rays, annotations, and patient folders are stored locally on the device unless you choose to share or back them up.

Can I export annotated measurements?

Yes. Pro exports come in 2 formats, JPEG and PDF, and include the annotated image, case metadata, and a clinical-use reminder for review documentation.

Does assisted detection make the final call?

No. Assisted detection is presented as a candidate measurement to review and adjust before saving or exporting.
