About
Something on your shelf might be breaking you out. Culprit helps you test it.
HOW IT WORKS
1. Scan the products you use. Culprit reads the ingredient list from a photo of the label and flags ingredients commonly reported to clog pores or irritate skin, adjusted for your skin type.
2. Take a 20-second selfie each morning. Culprit counts new spots by zone: forehead, nose, cheeks, chin and jaw. Sleep and steps from Apple Health and your city's humidity and UV fill in automatically, if you allow them.
3. Pause your top suspect. Culprit compares your skin with it and without it, the way a simple experiment would, and tells you honestly what it sees: it looks like it, it's not it, or it's unclear.
NO FOOD DIARY. NO GUESSING.
No journaling needed. One selfie a day, and the rest happens in the background.
HONEST BY DESIGN
• Culprit only names a suspect when your own data supports it. Often the answer is "unclear", and Culprit will say so.
• Ingredient flags are based on commonly reported effects. Everyone reacts differently.
• Culprit gives cosmetic guidance, not a diagnosis. If you have deep, painful or scarring breakouts, see a dermatologist.
YOUR PHOTOS STAY ON YOUR PHONE
Your photos are sent to Google's Gemini AI to be analysed, are not stored on Culprit's servers, and are kept only on your phone. Culprit's servers store only the spot counts. Apple Health data is read-only, summarised on your phone into daily totals, and never used for ads.
