Verdict
The clearest difference is in-app purchases: CDL Prep at none against CDL Pro's 5. CDL Prep also leads on ratings volume (6.7K vs 5) and chart position (#79 vs unranked). CDL Pro's advantage is ads (none vs shown) and update cadence (every 5 days vs every 2 months). On price, rating and device support there is nothing between them.

Both are free to download. CDL Pro sells 5 in-app purchases, starting at $5.99 per 7 days. CDL Prep asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.7 for CDL Prep against 4.6 for CDL Pro. That said, the two scores are not equally well evidenced: CDL Prep has 6.7K ratings behind it against 5, so its average is the more settled of the two. Written reviews are what separate them: 81% of CDL Prep's written reviews are positive against 100% of CDL Pro's.
CDL Prep ships an update every 2 months, CDL Pro every 5 days. The most recent releases landed on October 13, 2026 and October 4, 2026 respectively.
