# codeSpark vs LEGO® DUPLO® World

The clearest difference is rating: codeSpark at 4.6 against LEGO® DUPLO® World's 4.2. LEGO® DUPLO® World's advantage is ratings volume (201K vs 41K) and iOS requirement (13.0 vs 15.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. codeSpark sells 11 in-app purchases, starting at $3.99 per month and LEGO® DUPLO® World sells 11 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

codeSpark holds the better App Store score, 4.6 against 4.2. Both are backed by a comparable volume of ratings — 41K and 201K respectively. Written reviews complicate that: 52% of codeSpark's written reviews are positive against 54% of LEGO® DUPLO® World's, so the app with the better star average is not the one people write more warmly about.

codeSpark ships an update fortnightly, LEGO® DUPLO® World monthly. The most recent releases landed on October 22, 2026 and October 23, 2026 respectively.
