About

Scentech

Features
Read full description

The Scentech app controls your Scentech diffuser over Bluetooth, exactly the way you want it. Switch your diffuser on or off, choose when it should scent your home and how strongly. Set a schedule per day or pick one of the ready-made schedules, from early morning to late evening. The app remembers which scent is inside and how full the bottle is, and shows how many hours you have left. What you do in the app • Pair in a few steps: turn on Bluetooth, pick your diffuser, name the room. • Schedules per day: choose a ready-made schedule or draw your own times. • Intensity: from subtle to full, in one tap. • Scent tracking: see which scent is inside, how full the bottle is and how many hours remain. • Ambient light on or off on the Scentech 2 and Pro. • Several diffusers, each with its own name and schedule. • Reorder scents and diffusers without leaving the app, with your Scentech account: orders, package tracking and your scents in one place. Works with every Scentech diffuser (Lite, 2 and Pro). You need a Scentech diffuser to use the app. New in version 2.0: the app has been rebuilt from the ground up. Had the previous app? Pair your diffuser once more; a schedule already on the diffuser can be taken over right away.
