Nurtli is a calm, science-led skincare journal. Instead of telling you what to buy, it helps you notice what your own skin tends to respond to — over time, from your own logs. A microbiologist in your pocket: no hype, no brand deals, no good-or-bad verdicts. HOW IT WORKS Check in each day in a few taps — how your skin feels (Great, Fine, Off or Rough), anything you'd flag, the products you used, and a little life context. Over time, Nurtli quietly surfaces patterns: things that tend to appear near calmer days, and things worth watching. WHAT YOU CAN DO • Daily check-in — a 15-second read of your skin, with optional flags, lifestyle context, photos and notes. • Routine & products — build your AM/PM routine and a reusable product library, with full ingredient lists. • Ingredient library — hundreds of ingredients and microbes, explained through the lens of your skin barrier and microbiome, written by a microbiologist with citations. • Scan & learn — scan a product's barcode to read its ingredients, formula notes and allergen flags (Nurtli Plus). • Your patterns — the Nurtli Signal Engine finds gentle, observational patterns in your own logs, with trends, charts and honest confidence levels (Nurtli Plus). • Microbiome Minutes & Nurtli Notes — short reads and long-form, single-author science. No AI-generated content, ever. WHAT NURTLI WON'T DO • No scores, no traffic lights, no "good" or "bad" ingredients. • No product recommendations, no "buy this instead," no shopping links. • No AI run on your photos — they're a private memory aid, nothing more. • No diagnosing, no medical claims. Nurtli helps you observe; it doesn't treat. PRIVACY IS A FEATURE Your check-ins and photos stay on your device.
