## What is Scentdays?

■ Scent, delivered. Digitally.

Scentdays is a scent streaming platform that delivers and plays scents as digital content, the way you stream music or video.

Pair it with the Scent Gem smart diffuser, and the scent you choose in the app fills the room with a single tap. Scent Gem holds 12 base-scent cartridges and, much like a printer mixing four ink colors, precisely controls and combines their output to reproduce a wide range of scents.

■ What you can do

• Stream scents
Scent content that captures a moment—"After the Rain," "Folded Linen on Sunday"—ready to play to match your mood or the time of day.

• A rich catalog, curated
Browse by scent family (floral, woody, citrus and more), check the popularity rankings, or pick from scene-based recommendations to find today's scent.

• Collections
Bookmark the scents you love and organize them into your own collections. Your play history keeps them one tap away.

• Creator Mode
Blend the 12 cartridges to create an original scent of your own, and save it as a recipe.

• Easy sign-up with just an email
Create an account with only your email address. Your favorites and collections stay in sync across your devices.

■ Before you start

• Playing (diffusing) a scent requires the Scent Gem smart diffuser. Browsing the catalog, building collections, and saving blend recipes all work without the device.
• Scent Gem connects over Bluetooth.

■ About us

Scentdays is operated by Horizon Inc., the developer of Universal Scent Format, a universal format for scent data (Japanese Patent No. 7598522).
