# WISEcode UPF Detector vs Allergen Scout

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 (#79 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.

Both are free to download. Allergen Scout sells 2 in-app purchases, starting at $3.99 per month. WISEcode UPF Detector asks for nothing beyond the download.

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.

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.
