The clearest difference is rating: CDL Help at 4.9 against CDL Prep Hero's 4.0. CDL Help also leads on ratings volume (5.4K vs 2) and device support (3 vs 1). CDL Prep Hero's advantage is ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. CDL Help sells 5 in-app purchases, starting at $9.99 per 7 days and CDL Prep Hero sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CDL Help holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: CDL Help has 5.4K ratings behind it against 2, so its average is the more settled of the two.
