# AirKz vs Pollution

The clearest difference is rating: Pollution at 4.9 against AirKz's 1.0. Pollution also leads on review sentiment (83% vs 60%) and ratings volume (19 vs 1). AirKz's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price, update cadence, 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. AirKz asks for nothing beyond the download.

Pollution holds the better App Store score, 4.9 against 1.0. That said, the two scores are not equally well evidenced: Pollution has 19 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 60% of AirKz's written reviews are positive against 83% of Pollution's.
