# Goth AI vs Math.Brain

The clearest difference is update cadence: Math.Brain at every 8 days against Goth AI's monthly. Math.Brain also leads on rating (4.8 vs 4.6) and review sentiment (50% vs 39%). Goth AI's advantage is ratings volume (1.2K vs 91) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Goth AI sells 6 in-app purchases, starting at $6.99 per 7 days and Math.Brain sells 6 in-app purchases, starting at $12.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Math.Brain holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Goth AI has 1.2K ratings behind it against 91, so its average is the more settled of the two. Written reviews point the same way: 39% of Goth AI's written reviews are positive against 50% of Math.Brain's.

Goth AI ships an update monthly, Math.Brain every 8 days. Both last shipped on October 2, 2026.
