# WindAlert vs PredictWind

The clearest difference is update cadence: PredictWind at every 9 days against WindAlert's every 3 weeks. PredictWind also leads on ratings volume (33K vs 4.6K). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. WindAlert sells 10 in-app purchases, starting at $3.99 per month and PredictWind sells 16 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for WindAlert against 4.8 for PredictWind. That said, the two scores are not equally well evidenced: PredictWind has 33K ratings behind it against 4.6K, so its average is the more settled of the two. Written reviews are what separate them: 82% of WindAlert's written reviews are positive against 84% of PredictWind's.
