# Curiosity vs Brainjuice

The clearest difference is rating: Curiosity at 4.8 against Brainjuice's 4.2. Curiosity also leads on review sentiment (80% vs 39%) and ads (none vs shown). Brainjuice's advantage is update cadence (every 4 days vs every 2 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Curiosity sells 9 in-app purchases, starting at $7.99 per month and Brainjuice sells 8 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Curiosity holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Curiosity has 172 ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 80% of Curiosity's written reviews are positive against 39% of Brainjuice's.

Curiosity ships an update every 2 weeks, Brainjuice every 4 days. Both last shipped on October 16, 2026.
