# DiffuserStick vs 교체주기

The clearest difference is in-app purchases: 교체주기 at none against DiffuserStick's 1. 교체주기 also leads on ads (none vs shown) and update cadence (every 2 days vs every 12 months). DiffuserStick's advantage is iOS requirement (12.1 vs 18.5). On price and device support there is nothing between them.

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

DiffuserStick ships an update every 12 months, 교체주기 every 2 days. The most recent releases landed on October 30, 2026 and October 25, 2026 respectively.
