InciDecode turns any confusing ingredient label into a clear, honest read — and helps you track how your skin actually responds over time. WHAT IT DOES • Decode any label: paste the INCI ingredient list and see it matched against a curated database — comedogenic (pore-clogging) ratings, fragrance, drying alcohols and known irritants, all on-device. • Matched to your skin type: flags are tailored to oily, dry, combination, sensitive or normal skin, with a simple fit score for each product. • Grouped by function: actives, exfoliants and UV filters are highlighted so you know what a product really does. • Honest by design: anything not in the database is shown plainly as unrecognized — no guessing, no AI hand-waving. • Track your skin: a 5-second daily check-in builds a real 7-day trend and routine streak so you can see what's working. FREE CORE Label decoding and daily skin tracking are free — no forced trial, no account, no card required. INCIDECODE PRO InciDecode Pro is an optional auto-renewable subscription that unlocks smart morning and evening routine reminders, tailored to what's on your shelf (retinoid at night, SPF in the morning), with separate AM/PM times. Subscribing also supports the growth of the ingredient database — no ads, ever. Subscription: auto-renews unless canceled at least 24 hours before the period ends; payment is charged to your Apple ID at confirmation; manage or cancel anytime in your App Store settings. This app provides general skincare information only and is not a substitute for professional medical advice; consult your doctor or dermatologist before making any medical decisions.

The call

The clearest difference is ads: Think Dirty at none against InciDecode's shown. InciDecode's advantage is update cadence (every 6 days vs every 3 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
