# Nuddle vs Probability Quiz

The clearest difference is review sentiment: Probability Quiz at 100% against Nuddle's 43%. Nuddle's advantage is rating (4.9 vs 4.0) and ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Nuddle sells 3 in-app purchases, starting at $4.99 per month and Probability Quiz sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Nuddle holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: Nuddle has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 43% of Nuddle's written reviews are positive against 100% of Probability Quiz's, so the app with the better star average is not the one people write more warmly about.

Nuddle ships an update weekly, Probability Quiz every 5 days. The most recent releases landed on November 3, 2026 and October 24, 2026 respectively.
