ScentSignal tracks what fragrances actually sell for on the secondary market — full bottles, partial bottles, and decants from community resale listings — so you know a fair price before you buy or sell. FIND THE REAL PRICE Search almost any fragrance and see its market value estimate, adjusted for bottle size and fill level. Prices come from real listings, not retail sticker prices — and improved search helps you find the exact bottle you mean. GET ALERTED WHEN YOUR PRICE HITS Set a target price on a fragrance you're hunting and get a push notification when a matching listing shows up. Or watch for any new listing of a hard-to-find bottle. CATCH DEALS Browse listings priced below their market estimate, updated throughout the day. TRACK YOUR COLLECTION Keep shelves of what you own, want, and have tried. Add multiple bottles, sizes, and fill levels — even custom bottles — for a truer estimate of what your collection is worth, on a shareable collection page. EXPLORE EVERY FRAGRANCE A redesigned fragrance page brings prices, notes, and accords together in one place. Vote on accords and Scent DNA dimensions, leave ratings and reviews, and see how the community really experiences a scent — not just marketing copy. BUILT WITH THE COMMUNITY Spot something wrong or missing? Suggest updates and corrections right from the app. ScentSignal's catalog is constantly corrected and expanded by the people who use it.

Verdict

The call

ScentSignal's advantage is ratings volume (28 vs 3) and chart position (#175 vs unranked). On price, rating, ads and monetization model there is nothing between them.
