Smile Score: Overview
Smile Score is Smile Tracker's core expression metric. It combines lip geometry, eye crinkle (Duchenne marker), timing, and symmetry into a single 0–100 rating. Most users score between 50–85 depending on photo quality and expression type.

FAQ
What is a good Smile Score?
Scores above 70 indicate warm, engaging smiles. Above 85 suggests strong Duchenne markers and high symmetry.
Why did my score change between photos?
Lighting, angle, expression intensity, and genuine vs social smiling all shift scores. Consistent front-facing photos give the most stable results.
