This Really helped my eczema and acne. Would like honest feedback.
It's called SkinScholar. You can take a daily photo to track how your skin's actually changing over time with analysis, and scan a product to check whether its ingredients are likely to break you out. Also, you can log your skin day to day and it looks for patterns to find your triggers: products, or habits that keep setting you off.
i tried doing this in spreadsheets and notes for ages and it always fell apart, so i built the thing i wish i'd had.
it's on iOS and I hope it helps people who needed it like I did.
