# Dusts vs 미세먼지

The clearest difference is rating: Dusts at 4.6 against 미세먼지's 3.0. Dusts also leads on ads (none vs shown) and ratings volume (31 vs 1). 미세먼지's advantage is update cadence (every 4 days vs every 6 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Dusts holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: Dusts has 31 ratings behind it against 1, so its average is the more settled of the two.
