# Brainiac vs Dumerzel

The clearest difference is review sentiment: Dumerzel at 100% against Brainiac's 33%. Dumerzel also leads on rating (5.0 vs 4.8). Brainiac's advantage is ratings volume (261 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Brainiac sells 5 in-app purchases, starting at $6.99 per 7 days and Dumerzel sells 4 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

Dumerzel holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Brainiac has 261 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 33% of Brainiac's written reviews are positive against 100% of Dumerzel's.

Both ship on a similar rhythm, roughly every 8 days. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
