Sillage

A scent lingers in the doorway long after the person is gone — that soft trail is a sillage, and it is also a memory you can almost touch. This app is a quiet keeping-place for the smells that mark your life: rain on warm asphalt, your grandmother's kitchen, the salt of a coast you visited once. Open it and you step into a dim, amber-lit room where each remembered scent waits on its own card, unhurried and warm.

Every memory is composed like a real perfume — you build a small accord of three notes (a bright top, a beating heart, a grounding base) chosen from a gentle palette, and tie it to a place, a date and a mood. Attach a photo of the bottle or the moment, then lock the whole collection behind your fingerprint so it stays yours alone. The heart of the app is Waft: press it and a single half-forgotten scent drifts back up from your collection, inviting you to sit with that memory for a moment. Mark the ones you love, sort them by note or place, and let the room fill slowly with the perfume of your own days.
