Sillage

A scent is the quietest kind of memory, and it never asks permission before arriving. Sillage is a gentle place to keep the smells that stop you mid-step: rain on hot pavement, a grandmother's cedar drawer, the green bite of a snapped stem. Here each aroma becomes a small card with a note, a mood, and if you like, a photo of the moment it belonged to. The design is soft and unhurried, all warm greige and heather tones, so the app feels less like a database and more like an open window.

The heart of Sillage is the Accord Studio, where you blend three or four of your saved scent notes into a single named accord — your own private perfume drawn entirely from things you have actually smelled. Browse your collection as a calm vertical feed, filter by family (floral, woody, resinous, green, gourmand), and mark the ones that keep returning to you as favorites. A daily nudge invites you to pause and notice one scent in the world around you, and a soft haptic settles under your fingertips each time an accord comes together. Everything lives on your device, offline and unbothered.
