# CDL Study vs DMV Permit Test Prep

The clearest difference is ads: CDL Study at none against DMV Permit Test Prep's shown. CDL Study also leads on iOS requirement (13.0 vs 15.0). DMV Permit Test Prep's advantage is review sentiment (87% vs 55%) and update cadence (every 2 weeks vs every 4 months). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. CDL Study sells 2 in-app purchases, starting at $19.99 per month and DMV Permit Test Prep sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for CDL Study against 4.9 for DMV Permit Test Prep. That said, the two scores are not equally well evidenced: DMV Permit Test Prep has 21K ratings behind it against 2K, so its average is the more settled of the two. Written reviews are what separate them: 55% of CDL Study's written reviews are positive against 87% of DMV Permit Test Prep's.

CDL Study ships an update every 4 months, DMV Permit Test Prep every 2 weeks. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
