FarSight XR holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: FarSight XR has 243 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 67% of FarSight XR's written reviews are positive against 80% of Stars Units Sizes Objects's, so the app with the better star average is not the one people write more warmly about.
FarSight XR ships an update every 5 months, Stars Units Sizes Objects every 4 months. Both last shipped on October 24, 2026.
