A new study says if you're using a smartphone app to help you lose weight, you might not be getting your money's worth.
Researchers looked at 30 of the most popular weight loss apps on the market, and rated them on how many proven behavior strategies they included.
While many of them were good for tracking calories and calculating nutrition, most fell significantly short in motivating and encouraging users to stick with their plans.
But there's some good news for consumers: the study found that free apps were just as effective as the ones that cost you money.
That study was led by researchers at University of Massachusetts and published in 'American Journal of Preventative Medicine'.
