# ScratchJr vs BookTraps

The clearest difference is update cadence: BookTraps at every 10 days against ScratchJr's every 6 months. ScratchJr's advantage is ratings volume (1.8K vs 4) and iOS requirement (11.0 vs 13.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

On the App Store both sit at effectively the same score — 3.9 for ScratchJr against 3.8 for BookTraps. That said, the two scores are not equally well evidenced: ScratchJr has 1.8K ratings behind it against 4, so its average is the more settled of the two. Written reviews are what separate them: 67% of ScratchJr's written reviews are positive against 64% of BookTraps's.

ScratchJr ships an update every 6 months, BookTraps every 10 days. The most recent releases landed on October 17, 2026 and September 22, 2026 respectively.
