SiOsi Reviews — Discover what people think of this product.

One-selfie color analysis Upload a single photo and get your seasonal color type (one of the 12 seasons), your undertone, a gold vs silver verdict, and a personal palette with every shade named and copyable.

15 diagnostic makeup labs Grades the makeup you're actually wearing: foundation match, flashback, oxidation, coverage balance, pore visibility, transfer resistance, creasing, glitter fallout, and more.

Confidence scores on every verdict Each result carries a confidence score, and when the photo can't support a call (mixed lighting, heavy filter, low resolution), siOsi flags it instead of inventing an answer.

Photo-free season quiz Ten questions score undertone, depth, softness, and contrast as separate axes, then report an honest confidence bucket and name your runner-up season plus the axis that separates the two.

14 in-depth color analysis guides Full named palettes and the at-home tests that settle each question, including honest coverage of when those tests fail.

Shareable result pages Every analysis gets its own page you can send to a friend, a stylist, or your makeup artist.

9 languages English, Spanish, Portuguese, French, German, Italian, Russian, Ukrainian, Turkish. The whole product, not just the landing page.

Free tier without feature gates Your first analysis needs no account. Paying adds volume, never features: everything a paying user sees, a free user sees too.
