# FarSight XR vs Stars Units Sizes Objects

The clearest difference is rating: FarSight XR at 4.7 against Stars Units Sizes Objects's 4.3. FarSight XR also leads on ratings volume (243 vs 6). Stars Units Sizes Objects's advantage is review sentiment (80% vs 67%) and monetization model (ad-supported vs free with in-app purchases).

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

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.
