# Impostor Scanner vs Alien Blob io

Alien Blob io holds the better App Store score, 4.5 against 2.8. That said, the two scores are not equally well evidenced: Alien Blob io has 2K ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 58% of Impostor Scanner's written reviews are positive against 45% of Alien Blob io's, so the app with the better star average is not the one people write more warmly about.
