# Smart Tutors vs CDL Prep

The clearest difference is in-app purchases: Smart Tutors at none against CDL Prep's 5. Smart Tutors also leads on ads (none vs shown) and rating (5.0 vs 4.6). CDL Prep's advantage is ratings volume (3.4K vs 2) and chart position (#176 vs unranked). On price, device support and iOS requirement there is nothing between them.

Both are free to download. CDL Prep sells 5 in-app purchases, starting at $24.99 per month. Smart Tutors asks for nothing beyond the download.

Smart Tutors holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: CDL Prep has 3.4K ratings behind it against 2, so its average is the more settled of the two.
