BOSS811 holds the better App Store score, 4.0 against 2.8. That said, the two scores are not equally well evidenced: BOSS811 has 189 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of VMMap's written reviews are positive against 43% of BOSS811's, so the app with the better star average is not the one people write more warmly about.
VMMap ships an update every 2 months, BOSS811 monthly. Both last shipped on October 24, 2026.
