# CDL Prep vs CDL DMV Written Test

The clearest difference is in-app purchases: CDL DMV Written Test at none against CDL Prep's 5. CDL DMV Written Test also leads on update cadence (monthly vs every 3 months) and rating (4.9 vs 4.6). CDL Prep's advantage is chart position (#194 vs unranked) and review sentiment (80% vs 68%). On price, ratings volume, ads 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. CDL DMV Written Test asks for nothing beyond the download.

CDL DMV Written Test holds the better App Store score, 4.9 against 4.6. Both are backed by a comparable volume of ratings — 3.4K and 1.5K respectively. Written reviews complicate that: 80% of CDL Prep's written reviews are positive against 68% of CDL DMV Written Test's, so the app with the better star average is not the one people write more warmly about.

CDL Prep ships an update every 3 months, CDL DMV Written Test monthly. Both last shipped on October 25, 2026.
