# CDL Prep vs CDL Mastery

CDL Prep and CDL Mastery both sit at 4.8 stars, but that hides the real split: 100% of CDL Mastery's written reviews are positive against 50% of CDL Prep's. CDL Mastery also leads on update cadence (every 2 months vs every 8 months). CDL Prep's advantage is ratings volume (2.6K vs 363) and iOS requirement (15.1 vs 17.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. CDL Prep sells 2 in-app purchases, starting at $6.99 per 7 days and CDL Mastery sells 1 in-app purchase, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for CDL Prep against 4.9 for CDL Mastery. That said, the two scores are not equally well evidenced: CDL Prep has 2.6K ratings behind it against 363, so its average is the more settled of the two. Written reviews are what separate them: 50% of CDL Prep's written reviews are positive against 100% of CDL Mastery's.

CDL Prep ships an update every 8 months, CDL Mastery every 2 months. The most recent releases landed on September 26, 2026 and September 22, 2026 respectively.
