# Pollution vs Searu.io

The clearest difference is in-app purchases: Searu.io at none against Pollution's 10. Searu.io also leads on ads (none vs shown) and update cadence (weekly vs every 3 weeks). Pollution's advantage is ratings volume (18 vs 1). 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. Searu.io 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 Searu.io. That said, the two scores are not equally well evidenced: Pollution has 18 ratings behind it against 1, so its average is the more settled of the two.
