ooo: Face Symmetry Test

ooo measures your face's left–right symmetry from a single front-facing photo. Take one with the camera or choose one from your library.

■ Overall symmetry score
The left–right difference summed up as a number out of 100 (100 = no measured difference). It measures symmetry only, not appearance.

■ Mirrored faces
Swipe through the original, the flipped photo, and faces made perfectly symmetric from the left half or from the right half.

■ Detailed report
Midline tilt, left–right turn and up–down angle, plus how much higher one side sits at the eyebrows, outer eye corners and mouth corners, shown as percentages and degrees with the direction.

■ Asymmetry pattern
Based on which way the chin is shifted and how the eyes line up, the result is labelled Type 1–3 or Balanced. The type is a name for the measured pattern, not a diagnosis.

■ Live guidance while you shoot
The camera checks distance, centring, head angle, lighting and expression, tells you one thing to fix at a time, and takes the photo automatically once everything lines up.

■ Save and share
Save the photo you're viewing (original, flipped or mirrored) to Photos, or share it.

■ Your photos stay on your phone
Face detection and analysis run entirely on your device. Your photos are never sent to a server, and no account is needed.
