# DuBlox vs Nuddle

The clearest difference is in-app purchases: DuBlox at none against Nuddle's 3. DuBlox also leads on review sentiment (67% vs 43%) and iOS requirement (8.0 vs 13.0). Nuddle's advantage is update cadence (weekly vs every 2 months) and rating (4.9 vs 4.5). On price, ads and device support there is nothing between them.

Both are free to download. Nuddle sells 3 in-app purchases, starting at $4.99 per month. DuBlox asks for nothing beyond the download.

Nuddle holds the better App Store score, 4.9 against 4.5. Both are backed by a comparable volume of ratings — 2 and 8 respectively. Written reviews complicate that: 67% of DuBlox's written reviews are positive against 43% of Nuddle's, so the app with the better star average is not the one people write more warmly about.

DuBlox ships an update every 2 months, Nuddle weekly. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
