# PredictWind vs LuckGrib

The clearest difference is update cadence: PredictWind at every 11 days against LuckGrib's every 2 months. PredictWind also leads on ratings volume (33K vs 338) and chart position (#23 vs #185). LuckGrib's advantage is review sentiment (93% vs 84%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. PredictWind sells 16 in-app purchases, starting at $6.99 per month and LuckGrib sells 6 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 4.9 for LuckGrib. That said, the two scores are not equally well evidenced: PredictWind has 33K ratings behind it against 338, 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 93% of LuckGrib's.

PredictWind ships an update every 11 days, LuckGrib every 2 months. The most recent releases landed on October 15, 2026 and October 13, 2026 respectively.
