# Pudding Scan vs ApeSurvey

The clearest difference is monetization model: ApeSurvey at free with in-app purchases against Pudding Scan's subscription. ApeSurvey also leads on update cadence (fortnightly vs every 5 weeks) and review sentiment (100% vs 91%). Pudding Scan's advantage is rating (4.9 vs 4.5) and ratings volume (210 vs 2). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Pudding Scan sells 11 in-app purchases, starting at $0.99 per month and ApeSurvey sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Pudding Scan holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Pudding Scan has 210 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 91% of Pudding Scan's written reviews are positive against 100% of ApeSurvey's, so the app with the better star average is not the one people write more warmly about.

Pudding Scan ships an update every 5 weeks, ApeSurvey fortnightly. The most recent releases landed on October 14, 2026 and October 12, 2026 respectively.
