# Big Brain vs AI Homework Solver

The clearest difference is monetization model: AI Homework Solver at free with in-app purchases against Big Brain's subscription. AI Homework Solver also leads on rating (5.0 vs 4.6). Big Brain's advantage is update cadence (weekly vs every 2 months) and ratings volume (1.5K vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Big Brain sells 6 in-app purchases, starting at $1.99 per 7 days and AI Homework Solver sells 3 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

AI Homework Solver holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Big Brain has 1.5K ratings behind it against 1, so its average is the more settled of the two.

Big Brain ships an update weekly, AI Homework Solver every 2 months. The most recent releases landed on October 22, 2026 and October 20, 2026 respectively.
