About

Scent Stack

Features
Read full description

Photograph your fragrance shelf. Scent Stack reads the labels, then shows you something you can't see bottle by bottle: the shape of your whole collection. YOUR SCENT DNA One card that names what you collect and why it hangs together: your collection mapped across the nine families of the fragrance wheel, with the real proportions underneath. Amber 23%. Woody 15%. No guesswork. Swipe the card for the complete spectrum, then the note-by-note breakdown of everything you own. LAYERING THAT ACTUALLY WORKS Combinations built from bottles you already own, scored by a deterministic accord-affinity engine, never a chatbot's guess. Every pairing comes with how to wear it: which bottle first, how many sprays, and why that order. THE GAP WORTH FILLING Six wardrobe roles, from fresh daytime to cold-weather comfort. Scent Stack finds the one you're weakest in and suggests bottles that would fill it, priced near what's already on your shelf, and never in a family you've ruled out. If your collection is genuinely covered, it says so instead of inventing a reason to shop. WHAT DO YOU WANT TODAY Tap a mood, or describe the day in your own words: "beach wedding", "rainy interview", "something quiet". One decisive answer from your own bottles, with the reason. BUILT ON REAL METHOD The engines are deterministic and tested: the same shelf always gives the same answer. Performance is shown in honest bands rather than invented precision, and where perfumers genuinely disagree, the app says so. Your collection stays on your device. No account required. Scent Stack Full Access unlocks your complete Scent DNA card, every layering combination from the bottles you already own, and your gap analysis. Available as a yearly or weekly subscription; the exact price in your local currency is shown on this page and again in the app before any purchase is confirmed. Payment is charged to your Apple ID account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period.
