• Same DNA is stricter: a match now needs real notes in common, a similar dry-down and the same key materials, so the suggestions are closer to how the perfumes actually smell. • Friend requests and accepts show up right away, and you can follow back from a follower's menu. • Sign in is offered when you open the app. Close it to keep browsing without an account. • Fixed a problem where Sign in with Apple did nothing after Face ID on some iPhones.

Accounts are here, and they're optional. • Sign in with Apple or Google to save your shelf, wishlist and ratings. • Pick an avatar and a username, then follow friends and see the bottles they own. Only people you accept can see yours. • Your ratings now count towards each perfume's score. • Follow the official scentatlas profile to see our shelf. • Same DNA and Layering now compare the whole composition, from opening to dry-down, for more accurate matches. • Notes checked against brand sites and a second source across the catalogue.

A much bigger, smarter atlas. • Nearly 5,900 perfumes, with over 2,200 new ones, including Zara, Westside's Studiowest, Jo Malone London, and more from Chanel, Dior, Tom Ford and Kayali. • Every perfume now lists its notes, so every bottle shows up in the quiz, Tonight and your layering ideas. • Nykaa, Tira and Sephora are now sellers, and about 2,000 bottles show several shops with their prices side by side. • Known alternatives: the popular budget alternatives to the icons, shown on both perfumes' pages. • Same DNA now counts notes that play the same part, like bergamot and lemon, so close matches are easier to find. • The quiz reads what each perfume actually smells like, not just its label, and note picks match more precisely. • A price filter in the Atlas, and a page for every seller to browse what they stock. • The catalogue now updates between app versions: new perfumes, prices and links arrive on their own. • One page per perfume, with every seller in one list. No gift sets. Men's, women's and unisex tags corrected on over 150 bottles.

A new look, and a smarter atlas. • Redesigned from top to bottom: every bottle sits whole on white, with cleaner type and simpler screens. • Search understands typos and plain English, like "vanila for men under 5000". • Discover changes every day, and each shelf only shows bottles that truly fit its title. • Weather picks: choose a city or use your location, and Discover and Tonight suggest bottles for today's weather. • Same DNA is more accurate and shows the notes two bottles share. • I own it now suggests bottles that round out your collection. • Tonight has a Sports option for the gym. • Optional reminders: an evening pick from your shelf and a morning pick for the forecast. • The quiz hides options that would leave you with no matches.
