# Alien Shooter World vs StackUp

The clearest difference is ratings volume: Alien Shooter World at 1.1K against StackUp's 1. Alien Shooter World also leads on iOS requirement (16.6 vs 26.4). StackUp's advantage is rating (5.0 vs 4.7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Alien Shooter World sells 18 one-off in-app purchases and StackUp sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

StackUp holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Alien Shooter World has 1.1K ratings behind it against 1, so its average is the more settled of the two.
