Have you ever bought a diffuser and noticed that, at some point, the liquid no longer decreases and the scent no longer spreads? The sticks used in diffusers (reed sticks) have a limited lifespan. It is generally recommended to replace the sticks about once a month. The DiffuserStick app lets you record the date when you inserted the diffuser sticks along with a photo of your diffuser, and notifies you via push notification when it is time to replace them. Key Features • Add diffusers to your management list with photos and notes • Set diffuser stick replacement dates • Receive push notifications when it is time to replace the sticks • Move used diffusers to the archive for storage • Use widgets to quickly access and view your diffusers from the home screen
