Verdict
The clearest difference is ratings volume: Ventusky at 35K against PredictRain's 68. Ventusky also leads on chart position (#53 vs unranked) and update cadence (every 10 days vs every 3 weeks). On price, rating, review sentiment and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Ventusky sells 4 in-app purchases, starting at $4.99 per month and PredictRain sells 3 in-app purchases, starting at $6.99 per month. 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 Ventusky against 4.8 for PredictRain. That said, the two scores are not equally well evidenced: Ventusky has 35K ratings behind it against 68, so its average is the more settled of the two. Written reviews are what separate them: 77% of Ventusky's written reviews are positive against 71% of PredictRain's.
Ventusky ships an update every 10 days, PredictRain every 3 weeks. The most recent releases landed on November 4, 2026 and November 3, 2026 respectively.
