# Air Brakes Test Lite vs CDL Prep

Air Brakes Test Lite and CDL Prep both sit at 4.9 stars, but that hides the real split: 50% of CDL Prep's written reviews are positive against 0% of Air Brakes Test Lite's. CDL Prep also leads on ratings volume (2.6K vs 16). Air Brakes Test Lite's advantage is ads (none vs shown) and update cadence (every 2 months vs every 8 months). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Air Brakes Test Lite sells 2 in-app purchases, starting at $1.99 per month and CDL Prep sells 2 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Air Brakes Test Lite holds the better App Store score, 4.9 against 4.8. That said, the two scores are not equally well evidenced: CDL Prep has 2.6K ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 0% of Air Brakes Test Lite's written reviews are positive against 50% of CDL Prep's, so the app with the better star average is not the one people write more warmly about.

Air Brakes Test Lite ships an update every 2 months, CDL Prep every 8 months. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
