# CDL Prep Practice Test vs StudyPrime

The clearest difference is in-app purchases: StudyPrime at none against CDL Prep Practice Test's 15. StudyPrime also leads on rating (5.0 vs 4.8). CDL Prep Practice Test's advantage is ratings volume (2.3K vs 5) and update cadence (every 3 days vs every 2 weeks). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. CDL Prep Practice Test sells 11 in-app purchases, starting at $11.99 per 7 days. StudyPrime asks for nothing beyond the download.

StudyPrime holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: CDL Prep Practice Test has 2.3K ratings behind it against 5, so its average is the more settled of the two.
