# Sector 33 Classroom Edition vs Hello Tower

The clearest difference is price: Sector 33 Classroom Edition at Free against Hello Tower's $2.99. Sector 33 Classroom Edition also leads on in-app purchases (none vs 5) and review sentiment (100% vs 71%). Hello Tower's advantage is rating (4.4 vs 4.0) and ratings volume (66 vs 10). On ads and device support there is nothing between them.

Sector 33 Classroom Edition is free to download; Hello Tower costs $2.99 up front. Hello Tower sells 4 one-off in-app purchases. Sector 33 Classroom Edition asks for nothing beyond the download.

Hello Tower holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Hello Tower has 66 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 100% of Sector 33 Classroom Edition's written reviews are positive against 71% of Hello Tower's, so the app with the better star average is not the one people write more warmly about.
