Fly Go 4 holds the better App Store score, 4.1 against 3.7.

Written reviews complicate that: 36% of Fly Go 4's written reviews are positive against 71% of HS Sirius's, so the app with the better star average is not the one people write more warmly about.
Fly Go 4 ships an update every 4 weeks, HS Sirius every 3 weeks. The most recent releases landed on October 24, 2026 and October 20, 2026 respectively.
