# Q... vs Shatterbrain

The clearest difference is rating: Shatterbrain at 4.6 against Q...'s 2.7. Shatterbrain also leads on review sentiment (86% vs 51%) and ratings volume (436 vs 81). Q...'s advantage is update cadence (every 3 months vs every 11 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Q... sells 4 one-off in-app purchases and Shatterbrain sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Shatterbrain holds the better App Store score, 4.6 against 2.7. That said, the two scores are not equally well evidenced: Shatterbrain has 436 ratings behind it against 81, so its average is the more settled of the two. Written reviews point the same way: 51% of Q...'s written reviews are positive against 86% of Shatterbrain's.

Q... ships an update every 3 months, Shatterbrain every 11 months. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
