FormuLens helps you scan ingredient labels, decode INCI lists, compare products, and check how your routine works together. SCAN INGREDIENT LISTS Take a photo or import one from your library. Scan cleanser, serum, moisturizer, sunscreen, makeup, hair care, body care, and fragrance labels. If a label is long, scan it across multiple photos and the app combines the results. UNDERSTAND EACH INGREDIENT See what each ingredient is doing in the formula, from humectants and emollients to surfactants, preservatives, exfoliants, antioxidants, and fragrance components. FormuLens highlights key ingredients for the product type and calls out unusual ones that are worth a closer look. Tap any ingredient for a plain-language explanation and optional reference links. COMPARE PRODUCTS OR CHECK YOUR ROUTINE Compare products of the same type side by side to review shared ingredients, overall similarity, formula differences, and a simple verdict. Check a routine to review layering order, ingredient conflicts, overlap between steps, a build-up of EU-regulated fragrance allergens, and what may be missing. Scan a mixed collection when you want a clear per-product breakdown. SAVE PRODUCTS FOR LATER Keep products you analyze with a photo, custom name, tags, and notes. Search by name, tag, or ingredient, and filter by tag any time. PRIVATE BY DESIGN Ingredient analysis happens on your device. Your photos and scans stay with you. No account required.

Map Out Your Future Weeking isn't just about tracking the past; it’s about shaping what’s ahead. With the built-in long-term Planner, you can map out your biggest life goals and milestones by age.
