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.

  • 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.

You can also track manually - here's how.

 

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 dispay, 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.

Here's an example:

The WW food team identifies the ZeroPoint foods - highlighted above in yellow - that need to be deducted from the total SmartPoints value.

This ready meal contains a number of ZeroPoint foods, which lowers the SmartPoints value from 16 to 15 (in this case, on Green, Blue and Purple).

However, if a member attempted to add this ready meal themselves, the SmartPoints value will display as 16, rather than 15, as ZeroPoint foods haven't been accounted for. 

In a nutshell, the SmartPoints value returned for a crowdsourced food will always be higher than if it were a WW-approved food.

What are ZeroPoint foods? ZeroPoint foods form the foundation of a healthy pattern of eating, and should be considered 'go-to' choices when snacking and building meals. They don't need to be tracked because your SmartPoints Budget has already accounted for them - it factors in that you'll eat ZeroPoint foods as part of your daily life. Green, Blue and Purple each have a personalised amount of SmartPoints balanced with a curated list of ZeroPoint foods to ensure you reach your weight loss goals. 

 

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.

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.
