KPAX STORMTracker Weather holds the better App Store score, 4.7 against 3.6. That said, the two scores are not equally well evidenced: KPAX STORMTracker Weather has 695 ratings behind it against 30, so its average is the more settled of the two. Written reviews complicate that: 43% of StormTracker 21's written reviews are positive against 29% of KPAX STORMTracker Weather's, so the app with the better star average is not the one people write more warmly about.
StormTracker 21 ships an update every 6 weeks, KPAX STORMTracker Weather every 3 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
