# CDL Help vs CDL Prep Pro

The clearest difference is update cadence: CDL Help at every 2 days against CDL Prep Pro's every 5 weeks. CDL Help also leads on ratings volume (5.4K vs 2). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. CDL Help sells 23 in-app purchases, starting at $9.99 per 7 days and CDL Prep Pro sells 1 one-off in-app purchase. 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 CDL Help against 5.0 for CDL Prep Pro. That said, the two scores are not equally well evidenced: CDL Help has 5.4K ratings behind it against 2, so its average is the more settled of the two.

CDL Help ships an update every 2 days, CDL Prep Pro every 5 weeks. The most recent releases landed on October 25, 2026 and October 20, 2026 respectively.
