# Brain Test vs DOP 2

The clearest difference is chart position: Brain Test at #2 against DOP 2's unranked. Brain Test also leads on review sentiment (59% vs 49%) and ratings volume (1.5M vs 293K). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Brain Test sells 10 in-app purchases, starting at $3.99 per 7 days and DOP 2 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Brain Test holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Brain Test has 1.5M ratings behind it against 293K, so its average is the more settled of the two. Written reviews point the same way: 59% of Brain Test's written reviews are positive against 49% of DOP 2's.

Brain Test ships an update monthly, DOP 2 every 3 weeks. Both last shipped on October 28, 2026.
