# CDL Exam Expert vs CDL Prep

The clearest difference is monetization model: CDL Prep at free with in-app purchases against CDL Exam Expert's subscription. CDL Prep also leads on update cadence (every 2 months vs every 7 months) and ratings volume (153 vs 6). CDL Exam Expert's advantage is ads (none vs shown) and rating (4.8 vs 4.6). On price and in-app purchases there is nothing between them.

Both are free to download. CDL Exam Expert sells 3 in-app purchases, starting at $4.99 per month and CDL Prep sells 9 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

CDL Exam Expert holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: CDL Prep has 153 ratings behind it against 6, so its average is the more settled of the two.

CDL Exam Expert ships an update every 7 months, CDL Prep every 2 months. The most recent releases landed on June 1, 2026 and September 21, 2026 respectively.
