NeckCheck: Forward Head Angle

Forward head posture, checked from a single photo.

NeckCheck measures how far your head sits forward from one side-profile photo. It computes the craniovertebral angle (CVA) between the horizontal and the line from your shoulder to your ear, grades your posture, and tracks how it changes over time.

■ How it works
1. Prop your phone against a wall and stand about 1.5 m to the side.
2. When your side profile is in frame, a 5-second countdown starts and the photo is taken automatically.
3. The angle is computed from your ear and shoulder, then shown with a grade.

■ Result and grades
Your measured angle is drawn over the photo, and a gauge shows where you land on the healthy baseline (44° to 55°).
· Normal: 52° and above
· Borderline: 48° to 51°
· Caution: 44° to 47°
· Severe: below 44°
