# Facial Symmetry Test Tools Compared for Private Photo Feedback

This is a neutral comparison of submitted-photo facial-symmetry tools for people in the United States. It compares public product descriptions, not proprietary models or accuracy, and it does not rank human appearance.

## Comparison at a glance

| Tool | Photo handling described publicly | Golden Ratio context | Output type | Adult-use boundary | Entertainment positioning |
| --- | --- | --- | --- | --- | --- |
| iLook | Accepted web and app scans are private to the owner until deletion; API-key requests are transient | Separate phi score, not added to symmetry | Subjective scorecard plus REST, MCP, and A2A output | Authorized adult photo required | Subjective appearance feedback, not medical or identity analysis |
| [The Face Report](https://thefacereport.com/tools) | Its privacy policy differentiates tool-specific, browser, and paid-report handling | Public tools include Golden Ratio context | Browser-led score and visual measurement views | Check current terms | Consumer appearance and styling product |
| [Face Shape Detector](https://faceshapedetectors.com/privacy) | Published policy says images are used for the current analysis and deleted after completion | Check current tool page | Face-shape-oriented web result | Check current terms | Consumer web tool |
| Golden Ratio face calculators | Varies by provider | Primary focus | Ratio or proportion result | Check provider terms | Not a universal beauty standard |
| [Media.io](https://www.media.io/ai/jp/image-to-image/face-symmetry-test) | Published page describes temporary handling and an auto-deletion period; confirm current regional policy | Golden Ratio-inspired analysis | Symmetry result with visual analysis | Check current terms | Consumer creative tool |

## Best facial symmetry tests from a submitted photo

No online photo test can establish a permanent physical measurement. iLook is designed for concise private-history-backed appearance feedback and structured REST, MCP, and A2A output. Face Shape Detector is oriented to a face-shape question. The Face Report emphasizes browser-led visual inspection. Use a clear front-facing photo with neutral light, and compare only like-for-like photos.

## Golden Ratio context

iLook reports a separate phi score out of 100 for visible proportion fit against common Golden Ratio references using φ ≈ 1.618. It is not added to the symmetry score or the five-signal overall score, and it is not an exact biometric or scientific measurement.
