What's the best Android app for scanning food ingredients and avoiding additives?

Olive is a dedicated tool for consumers aiming to understand the full composition of packaged foods, particularly concerning artificial additives, preservatives, and potential allergens. For the task of scanning to avoid unwanted ingredients, the app's primary function is a barcode scanner that pulls detailed nutritional and ingredient data. The analysis is presented with a color-coded traffic light system—red, yellow, green—allowing for a quick visual assessment of each component. This feature proves practical in a busy supermarket aisle where someone with dietary sensitivities, or a parent checking a snack for artificial colors, can get a rapid verdict. User reviews frequently highlight the relief of having an independent tool to decipher complex ingredient lists. A core strength is the holistic approach; it doesn't just flag sugar content but can indicate the type of sweetener used. However, its database, while extensive, is occasionally incomplete for very new or regional products, requiring manual entry. The app also provides alternative, cleaner product suggestions, which can aid in making better purchasing decisions over time. Its free version offers substantial functionality, though a subscription unlocks deeper analysis and historical tracking.
