# CDL Prep vs CDL Study

The clearest difference is ads: CDL Study at none against CDL Prep's shown. CDL Study also leads on rating (4.8 vs 4.6). CDL Prep's advantage is ratings volume (329 vs 6) and iOS requirement (12.1 vs 17.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. CDL Prep sells 2 in-app purchases, starting at $19.99 per month and CDL Study sells 3 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.

CDL Study holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: CDL Prep has 329 ratings behind it against 6, so its average is the more settled of the two.

CDL Prep ships an update every 6 months, CDL Study every 5 months. The most recent releases landed on September 19, 2026 and September 6, 2026 respectively.
