The app, from first perfume to last spray
Search the catalog, read a perfume from top to base, sort the ones to try from the ones to buy, and keep a journal of what you wore. Shown with demo data on the app's own phone interface.
Three steps from a shelf of bottles to a collection you know
-
1
Add what you own
Photograph a bottle or a whole shelf, search the catalog by name, or import a list from a spreadsheet. Nothing is saved until you say so.
-
2
Rank it and wear it
Drag bottles into your own order, rate them, and log what you wear. Your journal fills in the stats.
-
3
Know before you buy
Keep a wishlist of what to try and what to buy, and see which of your own bottles smell close to anything you're eyeing.
Collection, shelf and wishlist
Bottles, decants and the ones you want, kept apart
Your shelf holds full bottles and decants; your wishlist holds what's next, in three lists: To try, To buy and Tried, with your verdict once you've smelled it. Every tile is tinted by its scent family, so a glance tells you what kind of collection you have.
- Search by name, house, note or your own tags
- Filter by family; sort by your rank, house, name or most worn
- A wishlist perfume moves to the shelf with "I bought it"
Perfume pages
See a perfume's notes in colour
Every perfume has its own page: the top, heart and base notes as the catalog lists them, each in the colour of its family with a small drawing, then the main accords, strongest first. Your rating, wears and notes sit beside them.
- A pyramid you can read at a glance: citrus, floral, woody, amber…
- Compare any two perfumes side by side, shared notes marked
- Facts come from the catalog; nothing is guessed
Alike in your collection
"You already have something like this"
Open any perfume and the app shows which of your own bottles smell close to it, and why: the notes they share and the accords they both lead with. Here, a well-known alternative to Aventus points straight back at the Aventus already on the shelf.
- "Very close" or "Quite close", by the same fixed bars for every pair
- Rarer shared notes count for more; bergamot and musk alone don't
- Worked out on your phone. Nothing is ranked or hidden
Add many at once
Photograph your shelf, tick what's yours
Take up to ten photos a day, four to six bottles each, labels facing the camera. AI lists the bottles it sees, and a bottle is ticked only when your phone's own reading of the label confirms it. Guesses are marked and never ticked for you.
- Already in your collection? It says so
- Choose bottles, decants or the wishlist once for the batch
- The photo is read and not kept. Nothing is saved until you tap Add
The crate, and your own order
Flip through your bottles like records
Switch the shelf to a crate of sleeves and swipe through it, one bottle at a time. Back on the grid, hold a bottle and drag it to where it belongs: your ranking is yours, and the app never reorders it.
- Hold, drag, drop: the others slide out of the way
- Or use Reorder, with Move up and Move down buttons
- Separate rankings for bottles, decants and the wishlist
Stats
What you actually wear
Log a wear in two taps and the numbers build themselves: wears by month, how much of your collection you've worn lately, how it grew, its note families and accords, most and least worn, and cost per wear when you've noted a price.
- A journal of every wear, with compliments and occasions
- "Not worn lately", for the bottles that deserve another go
- Counted on your phone, never sent
Shops near you · Singapore
Where to smell it before you buy it
A hand-checked list of 95 Singapore shops that sell perfume, sorted by how far they are from you. A perfume's page lists the shops that say they carry its house, with Directions in your own maps app.
- Your location is used on the phone only, never sent or stored
- Without it, shops are listed by postcode, or by distance from a place you pick
- Pop-ups carry their dates; the app never claims stock
Currency
Your currency, wherever the price was
Set your currency once. A price target keeps the currency you typed it in, and anything in another currency is shown converted, marked ≈, at the European Central Bank's daily reference rates.
- The amount you entered is never rewritten
- The rates' date is always shown
- A guide, not a rate to pay at
Privacy
Your collection lives on your phone
There is no account to make and nothing to sign in to. Your perfumes, ranks, notes, journal and settings are stored on your device, and nowhere else.
- No account. Open the app and start; delete it and everything it stored goes with it.
- No ads, no analytics, no tracking, in the app or on this site.
- Backups are files you keep. Move your whole collection to a new phone, or keep a copy, and it goes only where you send it.
- AI only when you ask. Ideas, descriptions and reading a label or a shelf photo go through our own service, counted for fair use; photos are not kept.
- Pictures and rates carry nothing about you. A bottle picture is asked for by its catalog number; the day's exchange rates are the same for everyone.
- Location stays put. Shops near you sorts on your phone; your location is never sent.
Questions
How do I get the app?
It's in beta. On iPhone, install Apple's TestFlight app, then open the beta link on your phone. On Android, email us with your Google Play email address; once you're on the testers list, opt in at the Play test page and install it from Google Play.
Why is it called The Smelly Index in the stores?
That's the name it's listed under in the App Store and Google Play for now. It's the same app.
Does it cost anything?
The beta is free.
Do I need an account?
No. There's no account and no sign-in. Your collection is kept on your phone.
How do I move my collection to a new phone?
Make a backup in Settings, send the file to yourself, and restore it on the new phone. It carries your perfumes, ranks, notes, wears and archive.
Does it work offline?
Yes. The catalog is on your phone, so searching, adding, ranking, logging wears and the stats all work without a connection. AI ideas, reading a shelf photo, bottle pictures and the day's exchange rates need one.
Where do the perfume facts come from?
From the app's catalog: house, name, year, perfumers, notes and main accords. What the app can't find stays blank rather than guessed. Descriptions are written by AI from the catalog's facts.
Does it tell me what to buy?
No. You rank, rate and decide. AI ideas in Explore are marked as such, each with its reason, and nothing the app suggests changes your lists until you act.
Is Shops near you only for Singapore?
For now, yes: 95 shops, checked by hand. More cities would each be a list of their own.
Which languages does it speak?
Sixteen: English, Arabic, Chinese, Dutch, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish and Turkish.
