Scent Memo helps fragrance evaluators, perfumers, and scent enthusiasts build a personal archive of fragrance samples and everyday scent memories. Record the details that matter: • Brand and product name• Scent category• Hedonic and strength ratings• Personal evaluation notes• Optional location• Up to three photos per record Whether you evaluate fragrances professionally, create fragrances, or record scents for yourself, Scent Memo keeps your observations organized and easy to revisit. Find memories quickly with Search and Filter. Explore records with saved map locations on the Map, and open the full entry from its location card. Your records and app-stored pictures remain on your device unless you export or share them. No account or sign-in is required. Location is optional, and Scent Memo does not track your location in the background. Map display and place-name resolution use Apple system services and may require a network connection. Use Backup Center to create and restore Full Backups, or import and export CSV files for spreadsheet access and data portability. Selected records can also be exported as CSV, HTML, or PDF, or copied as text or a table. An optional monthly reminder can help you remember to create a Full Backup before changing devices or deleting the app.

Verdict
The clearest difference is price: airx智能 at Free against Scent Memo's $0.99. airx智能 also leads on iOS requirement (14.0 vs 17.0). Scent Memo's advantage is update cadence (every 5 weeks vs every 19 months) and chart position (#199 vs unranked). On ads, in-app purchases and device support there is nothing between them.
