Verdict
The clearest difference is rating: Doyle Guides at 4.3 against PredictWind Race Tracker's 1.0. Doyle Guides also leads on ratings volume (50 vs 1).

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 Race Tracker sells 2 one-off in-app purchases and Doyle Guides sells 18 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
Doyle Guides holds the better App Store score, 4.3 against 1.0. That said, the two scores are not equally well evidenced: Doyle Guides has 50 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 78% of PredictWind Race Tracker's written reviews are positive against 60% of Doyle Guides's, so the app with the better star average is not the one people write more warmly about.
PredictWind Race Tracker ships an update every 6 weeks, Doyle Guides monthly. The most recent releases landed on September 3, 2026 and September 8, 2026 respectively.
