Verdict

The call

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.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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