# PredictWind vs Hygrometer

The clearest difference is ads: PredictWind at none against Hygrometer's shown. PredictWind also leads on review sentiment (84% vs 53%) and update cadence (every 9 days vs every 2 months). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. PredictWind sells 16 in-app purchases, starting at $6.99 per month and Hygrometer sells 2 one-off in-app purchases. 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 PredictWind against 4.7 for Hygrometer. That said, the two scores are not equally well evidenced: PredictWind has 33K ratings behind it against 6.1K, so its average is the more settled of the two. Written reviews are what separate them: 84% of PredictWind's written reviews are positive against 53% of Hygrometer's.

PredictWind ships an update every 9 days, Hygrometer every 2 months. The most recent releases landed on September 25, 2026 and September 22, 2026 respectively.
