Kodo is a contemporary aroma clock that releases different essential oils across the day, marking moments like waking, work, winding down, and sleep through scent rather than sound or sight. Fragrance is released through ultrasonic atomisers, dispersing a fine, consistent mist rather than relying on heat. The design draws on traditional East Asian incense clocks, reimagining the ritual of marking time through fragrance for a modern home. The 24-hour day is split into four segments, each tied to a specific fragrance and time of day. A companion app extends Kodo beyond the object itself, acting as both a controller and a guide to aromatherapy. Users can browse a database of essential oils, learn their properties and benefits, and buy their preferred oils through linked, trusted sources. Personalised fragrance sequences can be saved and recalled instantly, and a community marketplace lets users explore and adopt sequences shared by others, turning Kodo into a shared, evolving library of scent combinations rather than a single fixed routine.
