Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
