Cortex Onboard holds the better App Store score, 3.8 against 1.0. That said, the two scores are not equally well evidenced: Cortex Onboard has 12 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 56% of Cortex Onboard'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, Cortex Onboard every 2 months. The most recent releases landed on September 17, 2026 and June 7, 2026 respectively.
