# PredictWind vs Nullschool

The clearest difference is ratings volume: PredictWind at 33K against Nullschool's 27. PredictWind also leads on update cadence (every 9 days vs monthly) and chart position (#20 vs #175). Nullschool's advantage is review sentiment (100% vs 84%) and rating (5.0 vs 4.8). On price, ads, 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 Nullschool sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Nullschool 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 27, 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 Nullschool's.

PredictWind ships an update every 9 days, Nullschool monthly. The most recent releases landed on October 3, 2026 and October 2, 2026 respectively.
