# Critical Thinking Concepts vs Think Again

The clearest difference is review sentiment: Critical Thinking Concepts at 100% against Think Again's 50%. Critical Thinking Concepts also leads on rating (4.7 vs 3.5) and ratings volume (37 vs 2). Think Again's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (16.0 vs 18.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Critical Thinking Concepts sells 2 in-app purchases, starting at $3.99 per month and Think Again sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Critical Thinking Concepts holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: Critical Thinking Concepts has 37 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 100% of Critical Thinking Concepts's written reviews are positive against 50% of Think Again's.
