## What is Cologne Lab?

Your shelf, and the lab behind it.

Most fragrance apps stop at what you own. This one starts there and keeps going, all the way to blending your own.

TRACK WHAT YOU ACTUALLY WEAR

Add your bottles in seconds. Log a wear with one tap. Over time your shelf tells you something a list never could: what you reach for, as opposed to what you were talked into buying.

• Cost per wear on every bottle, so a 300 dollar bottle worn 60 times reads as 5 dollars a wear
• How much is left, estimated from your own spray count, with a correction when you top up or decant
• Your scent profile by note family, weighted by wears rather than by shelf count
• Batch codes, samples and decants tracked apart from full bottles
• A wishlist that stays out of your profile, because wanting something is not wearing it

NOTES FILLED IN FOR YOU

Type a name and the note pyramid fills itself in, on device. Nothing about your collection is uploaded, and when it does not recognise a fragrance it says so rather than inventing a plausible answer.

SAVE WHAT SMELLS GOOD TOGETHER

Layering combos, kept in application order, because the heavier scent goes on first and that is the part people forget.

THE BLENDING LAB

Design your own cologne with real numbers instead of guesswork.

• Compose in parts, then scale a 10 ml trial to a 100 ml batch with the ratio intact
• Every ingredient in drops, millilitres and grams at once, calibrated to your own dropper
• True pyramid balance, measured on neat aromatic volume rather than parts. Equal parts of neat bergamot and a ten percent musk reads as balanced everywhere else and is really ten to one citrus. This app tells you the truth.
• IFRA skin limits per material, checked against the finished bottle
• Cost per bottle and per millilitre, and nothing at all until every material is priced, because a partial total reads as complete and is always low
• Formula versions, so v1 survives while you try v2
• A maceration shelf that counts down four to six weeks and reminds you when a batch is ready
• A timed evaluation log at fifteen minutes, one hour, four hours and eight, on blotter and on skin

BUILT FROM YOUR BENCH

Register what you actually own and every suggestion is something you can mix tonight, not a shopping list.

WHAT IS FREE, AND WHAT IS NOT

Three bottles are free, with cost per wear, remaining volume and your taste profile, so you can see the app work before paying for it. Pro opens everything else: an unlimited wardrobe, layering combinations, the blending lab with its IFRA checks, pyramid and costing, formula versions, the maceration shelf and its reminders, the timed evaluation log, and the on-device blend suggestion.

Private by design. Your collection lives on your device and in your own iCloud. There is no account, no feed and no one else looking at your shelf. Subscriptions are handled by Apple and our billing provider; nothing about your fragrances is ever sent anywhere.
