ScentShelf is a perfume tracker and fragrance diary. Log your scent of the day, keep every bottle on one shelf, and let your own wear history show you your taste. Not an encyclopedia, and not a feed telling you what to buy. A personal record of what you actually wear, and what that says about you. No account needed to start. Open the app, add a bottle, log today's wear. Link an account later, only when you want a backup. DIARY: YOUR SCENT OF THE DAY Log what you wore in one tap and it lands on your calendar, so "what did I wear to that dinner in March?" finally has an answer. Add a mood and an occasion if you like: those tags gather into a monthly report, and a weekly recap card sums up your week, ready to share. SHELF: EVERY BOTTLE IN ONE PLACE Add a perfume from one sheet: type the name, or photograph the bottle with ScentScan, then send it to your shelf or your wishlist from the same place. Add photos, notes and impressions, group bottles into collections, choose how densely the shelf displays, and archive the ones you've finished without losing the memory. NEZ: ANSWERS FROM YOUR OWN SHELF Nez, the AI fragrance guide, now has its own tab. Ask what to wear tonight, what's in a collection, or which bottle you've been neglecting, and Nez answers from your shelf and your diary, not from a generic bestseller list. Simple questions about your own shelf are answered on the spot, without using a Nez question. Each day, Nez's Pick suggests something to wear; while your shelf is still small, it suggests perfumes worth trying instead, and any of them goes to your wishlist in one tap. INSIGHTS: FREE FOR EVERYONE See your most-worn bottles, the note families you reach for, and the moods behind them. Ask Nez for a read of your taste, built from what you actually wear. DISCOVER Editorial guides and reviews from fellow collectors. When something catches your eye, save it to your wishlist in one tap.

Your signature scent should be as layered as you are. Layer Accordingly is the first app built around YOUR fragrance collection — not someone else's "top 10" list. Add what you own, see how your bottles work together, and discover what to wear next based on your actual scent DNA. — FOUR TABS, ONE WARDROBE — COLLECTION Catalogue every bottle with its accord profile and notes. See your scent DNA emerge automatically — gourmand floral, woody amber, fresh chypre, whatever you naturally gravitate toward. Add custom fragrances and your own photos for anything we don't recognize. LAYERING Stop guessing what works together. Our compatibility engine analyzes the accords and notes in your collection and ranks every possible pair as Excellent, Good, or Subtle. Layer 2 or 3 fragrances at a time, save your favorites, build custom combos, rate every combination, and add personal notes for next time. DISCOVER Search 13,000+ fragrances from Sephora, Ulta, niche houses (Byredo, Le Labo, Maison Margiela, Henry Rose, Ellis Brooklyn, Initio, Fragrance Du Bois), to celebrity launches and budget finds. Filter by budget, your dominant accords, or the accords you're missing. FOR YOU Personalized daily picks rooted in your collection. Your Trifecta — three fragrances built around the notes you love. A seasonal edit that rotates Spring → Summer → Autumn → Winter automatically. A daily layering recommendation matched to the day's mood. All updated every morning. — BUILT FOR PRIVACY — No account required. No sign-up screen. Everything you add stays on your device — your collection, ratings, custom blends, and notes are yours alone. Delete the app or use "Delete all my data" inside Settings and it's gone instantly. — WHO IT'S FOR — Fragrance collectors who own more than three bottles. People stuck wearing the same scent every day. Anyone who's spent $200+ on a fragrance only to wonder if it'd be better with something else from the shelf. New collectors who want guidance instead of paralysis. — AFFILIATE DISCLOSURE — Layer Accordingly LLC is a participant in the Amazon Services LLC Associates Program.

Verdict

The call

The clearest difference is rating: ScentShelf Perfume Tracker at 4.5 against Layer Accordingly's 3.6. ScentShelf Perfume Tracker also leads on review sentiment (100% vs 62%). Layer Accordingly's advantage is ads (none vs shown) and monetization model (free vs freemium). On price, in-app purchases, device support and iOS requirement there is nothing between them.
