Getting healthy is often the number one resolution people make for the new year. This is an ambitious and very broad goal that can be broken down into several smaller steps, such as exercising more and eating better to lose weight.

Different surveys show different numbers, but the undisputed consensus is that most resolutions fail by February. Hundreds of mobile applications are available to help people avoid that outcome – which is the fate of over 90% of Americans who make resolutions.

These apps generally track health habits – anything from how many steps a person takes a day to how many calories they consume with every bite. Some have features designed to keep users motivated, such as competing against other users and being paid for achieving various health goals.

There is some scientific evidence that weight loss apps may actually help people shed extra pounds. Closely monitoring diet and physical activity may promote weight loss by increasing awareness of targeted behaviors and progress.

To identify the best apps for achieving weight loss resolutions, 24/7 Wall St. reviewed all weight loss apps in the App Store and Google Play. In order to be considered, the apps must be available for free download (although they may include ads or offer premium membership) on both platforms, have at least 10,000 reviews on each, and have an average rating of 4.5 or higher.

We then calculated the Apple and Google share of total reviews for each app, multiplied that number by the individual store rating for each app, and then took the average of the two for each app.

In the few cases in which two apps had the same average rating, the one with more total reviews was ranked higher.
