# Stacker vs KalyX.

The clearest difference is ads: KalyX. at none against Stacker's shown. KalyX. also leads on rating (5.0 vs 4.8) and device support (3 vs 1). Stacker's advantage is ratings volume (26 vs 1). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. Stacker sells 2 in-app purchases, starting at $69.99 per year and KalyX. sells 3 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.

KalyX. holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Stacker has 26 ratings behind it against 1, so its average is the more settled of the two.
