Tools within the Weight Watchers mobile app can only be accessed if the user has a Weight Watchers subscription. If the user has a subscription, they can track food, activity and weight, follow progress with the app's interactive chart, get tips for how to make healthy habits second nature based on location, and find workout ideas for any fitness level. In a recent survey that Weight Watchers conducted, Baylor College of Medicine found that even though Weight Watchers offer online and mobile tools, the biggest impact of the program exists within the meetings. Weight Watchers also recently introduced an app, Simple Start, that offers recipes for healthy eaters.
Azumio's Argus is built to be an intuitive, easy-to-use all day tracker. It tracks movement through a built-in passive tracking API, but it tracks food simplistically, using the phone's camera. Users just photograph food before they eat it and it shows up in Argus's visual timeline. Users can tag food with a food group, and the app has separate features to track coffee, soft drink and alcohol consumption. It's easy to use and might help someone get a general idea of how you're eating, but it doesn't track calories or specifics about the food.
SparkPeople is a free online weight loss program and Diet & Fitness Tracker is its premiere app. It has a database of 2 million foods, a separate tracker for water, and fitness and exercise features. It automatically backs up users' nutrition logs online as well. Although SparkPeople is free, when MobiHealthNews spoke with the company last February (after a JMIR study validated the effectiveness of the website), COO Dave Heilmann said paid apps were a big part of the site’s business model.
