Verdict
The clearest difference is price: Cognitive Biases at Free against Eventium's $3.99. Cognitive Biases also leads on in-app purchases (none vs 2) and rating (5.0 vs 4.7). Eventium's advantage is update cadence (every 2 weeks vs every 40 months) and ratings volume (378 vs 2). On ads, device support and iOS requirement there is nothing between them.
