# Impossible Quiz vs Brain Test

The clearest difference is rating: Brain Test at 4.8 against Impossible Quiz's 3.9. Brain Test also leads on ratings volume (1.5M vs 3.6K) and chart position (#2 vs unranked). Impossible Quiz's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Brain Test sells 10 in-app purchases, starting at $3.99 per 7 days. Impossible Quiz asks for nothing beyond the download.

Brain Test holds the better App Store score, 4.8 against 3.9. That said, the two scores are not equally well evidenced: Brain Test has 1.5M ratings behind it against 3.6K, so its average is the more settled of the two. Written reviews point the same way: 47% of Impossible Quiz's written reviews are positive against 59% of Brain Test's.

Impossible Quiz ships an update weekly, Brain Test monthly. The most recent releases landed on November 11, 2026 and November 12, 2026 respectively.
