RealSmile vs PrettyScale: Which Face Analyzer Is More Accurate?

The core difference: one score vs ten metrics

PrettyScale produces a single attractiveness percentage. It doesn't tell you why you scored that way, which features contributed, or what you could improve. Users report widely inconsistent results between sessions — the same photo can score differently on repeat visits, suggesting the algorithm isn't purely based on objective measurements.

RealSmile uses 68-point facial landmark detection running entirely in your browser. It measures 10 distinct facial metrics — canthal tilt, FWHR, jawline angle, symmetry, hunter eye index, and more — each with a percentile ranking against the population. If your jawline scores below average, you know exactly which metric to target and why.

RealSmile runs entirely in your browser — photos are never uploaded, stored, or processed on any server. PrettyScale uploads your photo to their servers for processing. For most users this isn't a dealbreaker, but it's a meaningful difference for sensitive use cases.

Which should you use?

If you want a quick curiosity score, PrettyScale works. If you want to understand your actual facial geometry, know which specific metrics are holding your score down, and get a ranked improvement plan — use RealSmile. The free scan takes the same amount of time.
