# Aphelion vs Kessler Cascade

The clearest difference is ads: Kessler Cascade at none against Aphelion's shown. Aphelion's advantage is ratings volume (21 vs 2). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Aphelion sells 1 one-off in-app purchase and Kessler Cascade sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Aphelion against 5.0 for Kessler Cascade. That said, the two scores are not equally well evidenced: Aphelion has 21 ratings behind it against 2, so its average is the more settled of the two.
