# PAX Training vs CDL Prep

The clearest difference is in-app purchases: PAX Training at none against CDL Prep's 5. PAX Training also leads on ads (none vs shown) and rating (4.8 vs 4.6). CDL Prep's advantage is ratings volume (3.2K vs 4) and update cadence (every 3 months vs every 15 months). On price and device support there is nothing between them.

Both are free to download. CDL Prep sells 5 in-app purchases, starting at $24.99 per month. PAX Training asks for nothing beyond the download.

PAX Training holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: CDL Prep has 3.2K ratings behind it against 4, so its average is the more settled of the two.

PAX Training ships an update every 15 months, CDL Prep every 3 months. The most recent releases landed on October 6, 2026 and October 20, 2026 respectively.
