Verdict

The call

The clearest difference is rating: Smart CDL at 5.0 against Official CLEP Exam Guide App's 2.7. Smart CDL also leads on update cadence (every 5 days vs every 6 weeks). Official CLEP Exam Guide App's advantage is ratings volume (131 vs 1) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
