# CDL Prep vs CDL Help

The clearest difference is in-app purchases: CDL Prep at none against CDL Help's 23. CDL Prep also leads on review sentiment (81% vs 54%) and chart position (#100 vs unranked). CDL Help's advantage is update cadence (every 4 days vs every 2 months) and rating (4.9 vs 4.7). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. CDL Help sells 20 in-app purchases, starting at $9.99 per 7 days. CDL Prep asks for nothing beyond the download.

CDL Help holds the better App Store score, 4.9 against 4.7. Both are backed by a comparable volume of ratings — 6.7K and 5.3K respectively. Written reviews complicate that: 81% of CDL Prep's written reviews are positive against 54% of CDL Help's, so the app with the better star average is not the one people write more warmly about.

CDL Prep ships an update every 2 months, CDL Help every 4 days. The most recent releases landed on September 24, 2026 and September 25, 2026 respectively.
