Formula Sift reads the ingredient list with you. Find a product by name, brand or barcode, and its formula opens in label order. Each ingredient comes with what it does, a clear definition, and the regulations that mention it in the EU, China, ASEAN, Japan, Korea and Canada. AT A GLANCE See whether a formula contains fragrance, alcohol, essential oils, colorants, preservatives, acids, retinoids, chemical sunscreens, silicones, mineral oil or sulfates. FOR EVERYONE AT HOME Give each person a profile: the ingredients they look out for, skin concerns, pregnancy or breastfeeding, and anything they would rather avoid. Every product is then checked against each profile, with a reason for every note. ALSO • More than 280,000 products and 40,000 ingredients, in English and Chinese • Directions, warnings, shelf life, SPF and PA, as printed on the label • Ingredients by INCI name, common name or CAS number • A collection for the products you return to FORMULA SIFT PRO Pro opens complete ingredient lists, the ingredients behind each check, and profile checks for your family. Searching, ingredient pages and regulatory information remain free. Important: Formula Sift is built for cosmetic ingredient review and personal preference tracking. It is not medical advice, diagnosis, or a substitute for professional guidance. Ingredient suitability can depend on concentration, product type, regulation, personal sensitivity, and actual use.

Verdict
The clearest difference is in-app purchases: Red Light Method Studio at none against Formula Sift's 3. Red Light Method Studio also leads on iOS requirement (16.6 vs 18.0). Formula Sift's advantage is update cadence (every 5 days vs every 3 weeks). On price, ads and device support there is nothing between them.
