# WindAlert vs CoastWarn

The clearest difference is ratings volume: WindAlert at 4.7K against CoastWarn's 1. WindAlert also leads on chart position (#67 vs unranked) and device support (4 vs 1). CoastWarn's advantage is rating (5.0 vs 4.8) and update cadence (every 6 days vs every 2 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. WindAlert sells 10 in-app purchases, starting at $3.99 per month and CoastWarn sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CoastWarn holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: WindAlert has 4.7K ratings behind it against 1, so its average is the more settled of the two.

WindAlert ships an update every 2 weeks, CoastWarn every 6 days. The most recent releases landed on October 27, 2026 and October 19, 2026 respectively.
