# PredictWind vs SeaState

The clearest difference is review sentiment: PredictWind at 84% against SeaState's 50%. PredictWind also leads on ratings volume (33K vs 3) and chart position (#23 vs unranked). SeaState's advantage is rating (5.0 vs 4.8). On price, update cadence, 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 SeaState sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

SeaState holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: PredictWind has 33K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 84% of PredictWind's written reviews are positive against 50% of SeaState's, so the app with the better star average is not the one people write more warmly about.

PredictWind ships an update every 11 days, SeaState every 2 weeks. The most recent releases landed on October 14, 2026 and October 5, 2026 respectively.
