Scanity
ShippedIngredient scanner for iOS and Android. Point it at a barcode and it resolves every additive through its E-numbers, trade names, and synonyms, then checks the result against the blocklist you built and gives you one verdict: Safe, Caution, or Danger. It covers 452,000+ products. There's no 0-100 score and there are no ads. Originally shipped in React Native, then rewritten in Swift and SwiftUI, with Skip transpiling that source into Jetpack Compose for Android.
