# Crazy scientist Lab Experiment vs Fly Challenge

The clearest difference is review sentiment: Crazy scientist Lab Experiment at 100% against Fly Challenge's 27%. Crazy scientist Lab Experiment also leads on in-app purchases (none vs 20) and ads (none vs shown). Fly Challenge's advantage is rating (4.2 vs 3.0) and ratings volume (1.3K vs 2). On price and device support there is nothing between them.

Both are free to download. Fly Challenge sells 20 one-off in-app purchases. Crazy scientist Lab Experiment asks for nothing beyond the download.

Fly Challenge holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: Fly Challenge has 1.3K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Crazy scientist Lab Experiment's written reviews are positive against 27% of Fly Challenge's, so the app with the better star average is not the one people write more warmly about.
