# OpenSnow vs Floodzilla

The clearest difference is in-app purchases: Floodzilla at none against OpenSnow's 3. Floodzilla also leads on rating (5.0 vs 4.7) and iOS requirement (15.1 vs 17.0). OpenSnow's advantage is ratings volume (9.1K vs 3) and update cadence (every 2 weeks vs every 2 months). On price, ads and device support there is nothing between them.

Both are free to download. OpenSnow sells 3 in-app purchases, starting at $49.99 per year. 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: OpenSnow has 9.1K ratings behind it against 3, so its average is the more settled of the two.

OpenSnow ships an update every 2 weeks, Floodzilla every 2 months. The most recent releases landed on September 28, 2026 and June 10, 2026 respectively.
