Protein tracker with a barcode scanner
Use the barcode on packaged food to find its protein information. Check the matching product, then enter the amount you ate to calculate your portion.
Scanning needs camera permission. Online product lookups need internet; coverage varies by product and country. Check available access and purchase options in the app.
A 45 g portion of a protein bar
1. Scan the packaging
Open the barcode scanner and point the camera at the product code. Protio first checks saved products, then can look online in Open Food Facts and USDA.
2. Compare with the label
Check the product name and protein per 100 g against your packaging. Recipes and database records can change; the source is shown with the result.
3. Enter your portion
Enter the grams you ate, rather than assuming a whole pack. Review the calculated protein and confirm the entry for your day.
What if the barcode is not found?
Scan the nutrition label, search for the food or create a product manually. When the label uses a serving or package basis, you need its gram weight to convert it to values per 100 g.
