# Card Ladder vs Slabline

Card Ladder and Slabline both sit at 4.9 stars, but that hides the real split: 100% of Slabline's written reviews are positive against 51% of Card Ladder's. Card Ladder's advantage is ratings volume (12K vs 6) and chart position (#9 vs unranked). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Card Ladder sells 2 in-app purchases, starting at $19.99 per month and Slabline sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Card Ladder against 5.0 for Slabline. That said, the two scores are not equally well evidenced: Card Ladder has 12K ratings behind it against 6, so its average is the more settled of the two.
