# ScratchJr vs Mi Story Builder

The clearest difference is rating: Mi Story Builder at 4.8 against ScratchJr's 3.9. Mi Story Builder also leads on update cadence (every 3 weeks vs every 6 months). ScratchJr's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Mi Story Builder sells 2 one-off in-app purchases. ScratchJr asks for nothing beyond the download.

Mi Story Builder holds the better App Store score, 4.8 against 3.9. That said, the two scores are not equally well evidenced: ScratchJr has 1.8K ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 67% of ScratchJr's written reviews are positive against 50% of Mi Story Builder's, so the app with the better star average is not the one people write more warmly about.

ScratchJr ships an update every 6 months, Mi Story Builder every 3 weeks. The most recent releases landed on October 19, 2026 and October 6, 2026 respectively.
