Weight Watchers Barcode Scanner review: Fastest, easiest way to track food points on your iPhone

Barcode Scanner is exactly what you need to easily find and enter PointsPlus values, and a great companion app to Weight Watchers Mobile for iPhone

If you're a Weight Watchers subscriber using Weight Watchers Mobile for iPhone, Weight Watchers Barcode Scanner is a great companion app for quickly calculating points values. Manually typing in fat, carbs, fiber, and protein can be a daunting task especially when grocery shopping. The barcode scanner app makes the task super simple and easier than ever, and is a great way to avoid impulse junk food purchases.

The biggest hurdle I've had to face since starting back up with Weight Watchers is grocery shopping. I've stuck with buying healthy foods but it can be a task to manually enter in the contents in order to decide whether or not a food I want is a healthy decision.

Sign in and Manage foods with WW Bardcode Scanner

The Weight Watches Barcode Scanner helps cut the time I spend looking for healthy foods in half while shopping. If you've used any type of QR code scanner on your iPhone you'll be right at home.

The first time you launch the app you'll be asked to sign into your Weight Watchers account. (You can choose for it to remember you in the Settings tab). Weight Watchers Barcode Scanner will load the scanner by default on launch. Then all you do is simply align a bar code and it scans away. It'll read it and tell you the PointsPlus value for a single serving. If it can't find an item, it'll allow you to manually enter in carbs, fat, fiber, and protein into the points calculator.

How to scan items with WW Barcode Scanner

If the app doesn't know the serving size it will simply say unknown. I've found most of the time that it calculates a points value but says unknown serving size, it's on items that are off-brand or measured in cups. You'll just need to follow the serving size on the box. If you can't get a good view of the bar code with the scanner, you can also choose to enter it in manually.

Add items directly to your tracker with WW Bardcode Scanner

Weight Watchers Barcode Scanner will also keep track of all the foods you've scanned under the Lists tab. Not only can you view the items you've added, you can add them to your favorites or your tracker directly from the application. Since Weight Watchers stores all your information online, you'll see the information added to your tracker via Weight Watchers Mobile as well next time you launch it.

There are a few apps in the app store that spit out Weight Watchers point values. I've found this one to be the best simply because it ties directly into your online tracker and integrates nicely as a companion app to the full Weight Watchers Mobile app. I don't have to jump out of whatever I'm using to scan bar codes and into Weight Watchers mobile and re-enter information. I just add the item I want directly to my tracker from Barcode Scanner and it's already there.

The good

  • It makes grocery shopping for healthier foods less of a task and not so overwhelming
  • Gives the option to add directly to your favorites and tracker which eliminates having to jump into another app
  • The overall UI is very similar to the Weight Watchers Mobile app so you'll feel right at home

The bad

  • You'll need a Weight Watchers subscription to utilize the application which may not be an option for some users as the cost may be more than they're willing to pay
  • You won't always find bar codes for many off brands
  • No auto-focus can be annoying at times when the app doesn't automatically center in on the bar code


If you're looking for an easier way to find PointsPlus values than typing in numbers each time, Weight Watchers Barcode Scanner is exactly what you're looking for and a great companion app to Weight Watchers Mobile for iPhone. While there are competitors out there, they just can't provide the tight integration into the Weight Watchers system that the official app can.

The fact that I can add things directly to my tracker and favorite items while I shop without jumping into multiple other apps makes it a hands down winner.

  • Nice to see you guys did a follow up to the WW App review. Love the WW app and Barcode scanner app too! For people who aren't WW members, the app "fooducate" offers a barcode scanner that will provide the PPV for most foods. I used that a lot before WW pushed their own app.
  • Funny you should mention that. I just reviewed Fooducate as well. Just hasn't went up yet. Are you reading my reminders list for imore? ;)
  • Hahah, that's so funny. You know what they say about great minds… I'll be on the lookout for that review too.
  • For anyone else who isn't or doesn't want to use Weight Watchers, there is another iPhone app that has the exact same scanner functionality. It's called MyNetDiary, and it comes in three flavors (free, fee, and subscription, all with varying degrees of functionality and support). I've been using MyNetDiary, and have been very happy with how comprehensive it is. In some respects, it's even easier than the WW app, does more, and isn't so Weight Watchers plan-centric.
  • Question...how do you guys prop up your phones for your photographs?
  • Littlemrdrummer pretty sure they use screen capture (top button on/off button and center toggle, pressed at the same time. That's what I do, pics are in your library and you can email it to yourself. Hope that helps.
  • Thanks so much for providing iniuvddials with such a remarkable chance to read from here. It is always very nice plus packed with a good time for me personally and my office peers to visit your web site more than thrice in one week to read through the latest guides you will have. And definitely, I'm also certainly fulfilled for the terrific methods you give. Selected 2 ideas in this posting are completely the finest I've had.
  • Oh...if it's the photos, the 4 and 4's stands on it's own.
  • I am a member of weight watchers but I attend meetings in person..not online. Can I use this app or is it for online ww members only? I downloaded it but it asks fo WW login and password. Where / how would i get login info? Thanks for any help or guidance you can give me. This looks like a great app!!
  • I used to be suggested this website by my cousin. I'm now not sure whether this publish is written by means of him as no one else understand such specified approximately my trouble. You are incredible! Thank you!
  • THANK YOU SO MUCH VOLTRON U RULE IT WORKED....even though my contacts are gone.....its ok (Happy Jailbreak owner)
  • Think of medifast as a band aid and not a cure.If your entaig junk food no matter how much or how little its not good for you. Eat fresh veggies, fruits, whole grains (limited grains) limited lean meats and low fat dairy. Then you wont have to worry bout portion control. Eventually after you get the junk cravings out of your body you want need as much to satisfy you. You don't have to eat to that feeling of uncomfortable. Eat a normal serveing of food take a break 9 times out of 10 you will be satisifed and if not chase it with some water melon. Most delcious filling food in the world.. ANd its in season!

  • I've been developing games using cocos2d-iphone for some time and was offen trapped with the Efficiency Problem. I was thinking about if it is possible to improve the engine using the STL-style template programming in the back-end ,rather than NSObject programming. Did cocos2d-iphone have plan about this? Or I wonder if I could contribute on it?
