The calories don't match the package
The numbers come from public food databases and from a serving size that may not match yours.

Steps
- Check the serving size on the food's detail screen. The numbers are for the amount shown. In the Food Diary, change the amount or the unit, or tap 0.5x, 1x, 1.5x or 2x. The units are weights and volumes only, not cups or spoons.
- Look at the small badge next to the name. In the Food Diary it names the data type, such as Foundation, Branded, Quick Picks or Barcode. In the Diet Log it says USDA, OFF or Local.
- In the Food Diary, look at the percent next to Data. A low number means many nutrients are missing for that food.
- Pick another result for the same food if one matches your package better.
- If none match, enter the numbers from your package yourself. In the Diet Log, tap Enter manually.
Why the numbers differ
USDA FoodData Central and Open Food Facts are large public databases. A product can change after its entry was made, or an entry can be for a different size or country.
Package labels round their numbers, so a small gap is normal. The nutrition note in the app says these numbers are general estimates, not a plan made for you.
When a food has no calorie number
Some foods come with protein, carbs and fat but no energy value. SOS then adds them up with a standard estimate, so the food does not show zero.
Some Open Food Facts products list energy in kilojoules only. SOS turns that into calories. A product with no energy value at all cannot be logged from its barcode.
Totals can include more than food
In the Food Diary, the day total can include calories from supplements you track. The ring says when it does. The Diet Log does not add supplements.
