# Alien World vs Comet Trails

The clearest difference is review sentiment: Comet Trails at 100% against Alien World's 47%. Comet Trails also leads on rating (5.0 vs 4.5). Alien World's advantage is ratings volume (2.1K vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Alien World sells 7 one-off in-app purchases and Comet Trails sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Comet Trails holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Alien World has 2.1K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 47% of Alien World's written reviews are positive against 100% of Comet Trails's.
