Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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