# FloodWatch vs Floodzilla

The clearest difference is in-app purchases: Floodzilla at none against FloodWatch's 5. Floodzilla also leads on ads (none vs shown) and rating (5.0 vs 4.7). FloodWatch's advantage is ratings volume (314 vs 3). On price, update cadence and device support there is nothing between them.

Both are free to download. FloodWatch sells 5 one-off in-app purchases. Floodzilla asks for nothing beyond the download.

Floodzilla holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: FloodWatch has 314 ratings behind it against 3, so its average is the more settled of the two.
