# CDL Prep vs Primary Tradeline

The clearest difference is review sentiment: CDL Prep at 80% against Primary Tradeline's 0%. CDL Prep also leads on rating (4.6 vs 1.0) and ratings volume (3.2K vs 3). Primary Tradeline's advantage is ads (none vs shown). On price, in-app purchases, monetization model 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 and Primary Tradeline sells 11 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

CDL Prep holds the better App Store score, 4.6 against 1.0. That said, the two scores are not equally well evidenced: CDL Prep has 3.2K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 80% of CDL Prep's written reviews are positive against 0% of Primary Tradeline's.
