Verdict

The call

The clearest difference is in-app purchases: BRAIN at none against IQ Test's 11. BRAIN also leads on rating (4.7 vs 4.4) and review sentiment (50% vs 35%). IQ Test's advantage is update cadence (every 6 weeks vs every 27 months) and ratings volume (8K vs 3). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

BRAIN holds the better App Store score, 4.7 against 4.4.
