# WeatherTrack GRIB vs PredictWind

The clearest difference is price: PredictWind at Free against WeatherTrack GRIB's $9.99. PredictWind also leads on ratings volume (33K vs 158) and update cadence (every 9 days vs every 6 weeks). On rating, review sentiment, ads and in-app purchases there is nothing between them.

PredictWind is free to download; WeatherTrack GRIB costs $9.99 up front. WeatherTrack GRIB sells 10 in-app purchases, starting at $2.99 per 7 days 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 — 4.7 for WeatherTrack GRIB against 4.8 for PredictWind. That said, the two scores are not equally well evidenced: PredictWind has 33K ratings behind it against 158, so its average is the more settled of the two. Written reviews are what separate them: 89% of WeatherTrack GRIB's written reviews are positive against 84% of PredictWind's.

WeatherTrack GRIB ships an update every 6 weeks, PredictWind every 9 days. The most recent releases landed on October 21, 2026 and October 23, 2026 respectively.
