# Unistellar vs Telescopius

The clearest difference is ratings volume: Unistellar at 100 against Telescopius's 8. Telescopius's advantage is review sentiment (54% vs 45%) and iOS requirement (15.0 vs 18.0). On price, rating, ads and in-app purchases there is nothing between them.

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

Unistellar holds the better App Store score, 3.8 against 3.6. That said, the two scores are not equally well evidenced: Unistellar has 100 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 45% of Unistellar's written reviews are positive against 54% of Telescopius's, so the app with the better star average is not the one people write more warmly about.
