# DiffuserStick vs 오늘의 행복

The clearest difference is in-app purchases: 오늘의 행복 at none against DiffuserStick's 1. 오늘의 행복 also leads on ads (none vs shown) and update cadence (every 2 months vs every 12 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. DiffuserStick sells 1 one-off in-app purchase. 오늘의 행복 asks for nothing beyond the download.

DiffuserStick ships an update every 12 months, 오늘의 행복 every 2 months. Both last shipped on October 30, 2026.
