# PredictWind vs DiveSight

The clearest difference is ratings volume: PredictWind at 33K against DiveSight's 24. PredictWind also leads on chart position (#18 vs unranked) and iOS requirement (15.5 vs 26.0). DiveSight's advantage is review sentiment (100% vs 84%) and 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 DiveSight sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

DiveSight 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 24, so its average is the more settled of the two. Written reviews point the same way: 84% of PredictWind's written reviews are positive against 100% of DiveSight's.

PredictWind ships an update every 9 days, DiveSight weekly. The most recent releases landed on October 4, 2026 and September 26, 2026 respectively.
