# CDL Study vs CDL Pass

The clearest difference is in-app purchases: CDL Pass at none against CDL Study's 3. CDL Pass also leads on update cadence (weekly vs every 5 months) and ratings volume (164 vs 6). CDL Study's advantage is ads (none vs shown). On price, rating and device support there is nothing between them.

Both are free to download. CDL Study sells 3 in-app purchases, starting at $24.99 per month. CDL Pass asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.8 for CDL Study against 4.9 for CDL Pass. That said, the two scores are not equally well evidenced: CDL Pass has 164 ratings behind it against 6, so its average is the more settled of the two.

CDL Study ships an update every 5 months, CDL Pass weekly. The most recent releases landed on September 21, 2026 and October 2, 2026 respectively.
