# PredictWind Race Tracker vs ACR Product App

The clearest difference is review sentiment: PredictWind Race Tracker at 78% against ACR Product App's 22%. ACR Product App's advantage is rating (1.5 vs 1.0) and in-app purchases (none vs 2). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. PredictWind Race Tracker sells 2 one-off in-app purchases. ACR Product App asks for nothing beyond the download.

ACR Product App holds the better App Store score, 1.5 against 1.0. That said, the two scores are not equally well evidenced: ACR Product App has 31 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 22% of ACR Product App'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, ACR Product App every 2 months. The most recent releases landed on September 3, 2026 and August 7, 2026 respectively.
