How to use the Barcode Scanner

Tracking has never been quicker or simpler.

How to track foods using the barcode scanner


To quickly track a food, take advantage of one of the coolest features in the WW app, our barcode scanner.

For IOS

  • Tap the barcode icon next to the 'Search Food' bar at the top of your My Day screen.

  • Align the box that pops up on your screen with the product barcode until it scans (this should only take a few seconds).

  • If the item is a WW-verified food (a food added by qualified WW nutritionists), all of the information you need will display, including the SmartPoints value and nutritional data. Edit serving or portion size accordingly, then tap 'Track' to track to My Day.

For Android

  • Tap the barcode icon in the Search bar on your My Day screen.

  • Align the box that pops up on your screen with the product barcode until it scans (this should only take a few seconds).

  • If the item is a WW-verified food (a food added by qualified WW nutritionists), all of the information you need will display, including the SmartPoints value and nutritional data. Edit serving or portion size accordingly, then tap 'Track' to track to My Day.

You can also track manually—here's how.

Scan at the supermarket


In addition to helping you track your food, the barcode scanner also comes in handy at the supermarket! Use it to scan items on the shelves to find the SmartPoints value and decide whether it will fit into your Budget this week.


Advanced barcode scanning


Some foods are member-added


If you scan a barcode and it doesn't exist in our database, a selection of member-added foods similar to the item you scanned will display, which you can then choose to track.

Please note, these are not WW-verified foods. We call these crowdsourced foods, which means members input their own nutritional data to generate a SmartPoints value.

Crowdsourced foods are reliant on people inputting the data correctly, so can potentially be inaccurate. We recommend you cross-check nutritional data before tracking.


Crowdsourcing and ZeroPoint™ foods


When it comes to member-added or crowdsourced foods, the SmartPoints algorithm does not account for ZeroPoint foods.

All SmartPoints values for WW-verified foods containing ZeroPoint foods are calculated by our in-house team of qualified nutritionists, who adjust the SmartPoints value based on ZeroPoint ingredients.

If a member adds a food item that is either a ZeroPoint food or contains ZeroPoint foods, the incorrect SmartPoints value will be generated.

The SmartPoints value returned for a crowdsourced food will always be higher than if it were a WW-approved food.

How to add a food


If you scan a barcode and it doesn't return any results, or another member has added the item but the nutritional data is wrong, you can add the item yourself.

  • Scan the item's barcode, then tap 'Create food'.
  • Add values into the required fields—including calories, protein, sugar and saturated fat—to generate a SmartPoints value. Remember to adjust the portion size.
