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. FEATURES - Daily SOTD wear log on a scrollable calendar - Mood and occasion tags, a monthly report and a shareable weekly recap - Collection manager with wishlist, archive and adjustable shelf density - One Add sheet: type a name or scan the bottle - Nez, an AI guide grounded in your own shelf and diary - Free Insights: most worn, note families, moods - A daily Nez Pick - Editorial guides and community reviews - Home Screen widget with today's Nez Pick (Pro) - Works on iPhone Duo, with a side rail on the outer display FREE Up to 10 perfumes with unlimited wear logging, the full calendar, mood and occasion tags, Insights and the monthly report.
