# CDL Prep  vs Trap Chess

The clearest difference is in-app purchases: Trap Chess at none against CDL Prep 's 4. CDL Prep 's advantage is ratings volume (75 vs 1) and iOS requirement (13.0 vs 15.2). On price, rating, ads and device support there is nothing between them.

Both are free to download. CDL Prep  sells 4 in-app purchases, starting at $7.99 per 7 days. Trap Chess asks for nothing beyond the download.

Trap Chess holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: CDL Prep  has 75 ratings behind it against 1, so its average is the more settled of the two.
