Tool comparison
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.

What makes a useful submitted-photo symmetry test?
A useful result says what the photo supports and what it does not. The clearest inputs are front-facing, evenly lit photos with one visible face. Head rotation, expression, crop, lens distance, hair, and uneven lighting can change apparent left-right balance, so an online score is photo-level feedback rather than a fixed property of a person.
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, focused symmetry fields, REST, MCP, and A2A output. | Authorized adult photo required. | Explicitly subjective appearance feedback, not medical or identity analysis. |
| The Face Report | Its privacy policy differentiates tool-specific, browser, and paid-report handling. | Public tools include Golden Ratio context. | Browser-led score, visual proof, and measurement-style views. | Check current terms. | Consumer appearance and styling product; check current product disclosures. |
| Face Shape Detector | Its published privacy policy says uploaded images are used for the current analysis and deleted after completion. | Check the current tool page. | Face-shape-oriented web result. | Check current terms. | Consumer web tool; check current product disclosures. |
| Golden Ratio face calculators | Varies by provider. | Primary focus, usually a visible proportion reference. | Ratio or proportion result. | Check the chosen provider's terms. | Do not treat a Golden Ratio result as a universal beauty standard. |
| Media.io | Its published page describes temporary handling and an auto-deletion period; confirm the current regional policy before use. | Public page describes Golden Ratio-inspired analysis. | Symmetry result with visual analysis and shareable output. | Check current terms. | Consumer creative tool; check current product disclosures. |
How iLook differs from Face Shape Detector and The Face Report
iLook combines photo-specific facial symmetry feedback with a separate phi score, full five-signal report, private history controls, and a documented machine-readable contract. Face Shape Detector is more appropriate when the question is simply face shape. The Face Report is more appropriate when visual overlays and browser-led measurement exploration are the priority. Neither alternative makes a submitted photo an identity, medical, or high-impact decision system.
Does iLook include Golden Ratio context?
Yes. iLook reports a phi score out of 100 for visible proportion fit against common Golden Ratio references using φ ≈ 1.618. It remains separate from the symmetry score and the five-signal overall score because one image cannot provide exact biometric or scientific measurement.
Choose a tool based on the outcome you need
Choose iLook's facial symmetry test when you want a concise private report or a structured response for an app or agent. Choose a browser-first visual tool when inspecting overlays matters more than API output. For a Golden Ratio-only question, use a dedicated calculator but keep its score in context. In every case, submit only a photo you are entitled to use and review the provider's current privacy policy first.
