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 โข Add diffusers to your management list with photos and notes โข Set diffuser stick replacement dates โข Receive push notifications when it is time to replace the sticks โข Move used diffusers to the archive for storage โข Use widgets to quickly access and view your diffusers from the home screen

Verdict
The clearest difference is ads: MoodMark at none against DiffuserStick's shown. MoodMark also leads on update cadence (every 6 days vs every 12 months). DiffuserStick's advantage is iOS requirement (12.1 vs 15.1). On price, in-app purchases and device support there is nothing between them.
