# Save the Planet 3D vs Car Assembly Simulator

The clearest difference is rating: Car Assembly Simulator at 4.7 against Save the Planet 3D's 1.9. Car Assembly Simulator also leads on ratings volume (1.3K vs 8). Save the Planet 3D's advantage is in-app purchases (none vs 13) and review sentiment (50% vs 20%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Car Assembly Simulator sells 13 one-off in-app purchases. Save the Planet 3D asks for nothing beyond the download.

Car Assembly Simulator holds the better App Store score, 4.7 against 1.9. That said, the two scores are not equally well evidenced: Car Assembly Simulator has 1.3K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 50% of Save the Planet 3D's written reviews are positive against 20% of Car Assembly Simulator's, so the app with the better star average is not the one people write more warmly about.
