Change4Life Food Scanner is a free lifestyle app from Public Health England that aims to help users make healthier food and drink choices. The app uses augmented reality to bring to life what's inside your food and drink right in front of your eyes. The app is based on the most widespread data available to the developers, and they are continuously working to improve it and adding more products all the time.

With the Food Scanner app, you can find out how much sugar, salt, and saturated fat is in your food and drink by scanning the barcode. The app shows the number of sugar cubes, salt sachets, and saturated fat lumps based on grams per pack/100g/ml/portion when that information is available. The app also provides information on the weight of one sugar cube, one saturated fat lump, and one salt sachet.

Overall, Change4Life Food Scanner is a useful app for those interested in making healthier food and drink choices. It is easy to use and provides helpful information on the nutritional value of various products.
