Verdict
The clearest difference is ads: PredictWind at none against Mountain's shown. PredictWind also leads on update cadence (every 9 days vs every 2 months) and ratings volume (33K vs 707). On price, rating, in-app purchases and monetization model 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. PredictWind sells 16 in-app purchases, starting at $6.99 per month and Mountain sells 2 in-app purchases, starting at $3.99 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 PredictWind against 4.9 for Mountain. That said, the two scores are not equally well evidenced: PredictWind has 33K ratings behind it against 707, 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 74% of Mountain's.
PredictWind ships an update every 9 days, Mountain every 2 months. The most recent releases landed on September 30, 2026 and September 29, 2026 respectively.
