Verdict

The call

The clearest difference is in-app purchases: WISEcode UPF Detector at none against Allergen Scout's 2. WISEcode UPF Detector also leads on ratings volume (1.8K vs 6) and chart position (#83 vs unranked). Allergen Scout's advantage is rating (5.0 vs 4.7) and iOS requirement (14.0 vs 17.6). On price, review sentiment, update cadence and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Allergen Scout holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: WISEcode UPF Detector has 1.8K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 84% of WISEcode UPF Detector's written reviews are positive against 80% of Allergen Scout's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

WISEcode UPF Detector ships an update every 2 weeks, Allergen Scout every 3 weeks. The most recent releases landed on November 4, 2026 and October 30, 2026 respectively.
