Verdict
Brain Test and Impossible Quiz both sit at 4.8 stars, but that hides the real split: 100% of Impossible Quiz's written reviews are positive against 58% of Brain Test's. Impossible Quiz also leads on in-app purchases (none vs 12) and iOS requirement (12.0 vs 15.0). Brain Test's advantage is ratings volume (1.5M vs 25) and update cadence (monthly vs every 4 months). On price, rating, ads and device support there is nothing between them.
