# Pollution vs 粉度

The clearest difference is in-app purchases: 粉度 at none against Pollution's 10. 粉度 also leads on ads (none vs shown) and update cadence (every 10 days vs every 3 weeks). Pollution's advantage is review sentiment (83% vs 66%) and ratings volume (19 vs 3). On price, rating, device support and iOS requirement there is nothing between them.

Both are free to download. Pollution sells 10 in-app purchases, starting at $1.19 per 7 days. 粉度 asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Pollution against 5.0 for 粉度. That said, the two scores are not equally well evidenced: Pollution has 19 ratings behind it against 3, so its average is the more settled of the two. Written reviews are what separate them: 83% of Pollution's written reviews are positive against 66% of 粉度's.

Pollution ships an update every 3 weeks, 粉度 every 10 days. The most recent releases landed on November 7, 2026 and November 5, 2026 respectively.
