# CNA Practice Exam Prep vs K

The clearest difference is review sentiment: K at 100% against CNA Practice Exam Prep's 50%. K also leads on update cadence (every 5 days vs every 2 months) and rating (5.0 vs 4.6). CNA Practice Exam Prep's advantage is ratings volume (213 vs 1) and iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. CNA Practice Exam Prep sells 2 in-app purchases, starting at $24.99 per month and K sells 5 in-app purchases, starting at $16.99 per month. Whichever you choose, the download price is not the number that matters.

K holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: CNA Practice Exam Prep has 213 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 50% of CNA Practice Exam Prep's written reviews are positive against 100% of K's.

CNA Practice Exam Prep ships an update every 2 months, K every 5 days. The most recent releases landed on October 22, 2026 and October 12, 2026 respectively.
