Project OnTrack

Smartphone apps can be great tools for weight control for many reasons. Our phones are typically with us, or within very close reach, for most of the day which means we can rely on it to track our eating and activity behavior. You can also count on your phone in a time of need, such as when you need to quickly calculate the calories in a particular food or when you need some distraction from a temptation.

However, if you have been on the app store lately you know that there seem to be an infinite number of apps for weight loss. Unfortunately, many of those apps are not ‘empirically supported’. This term means that the app has been used in research studies and has been proven successful in producing weight loss when compared to some alternative. Not many studies like this have been done and this means that even experts in behavioral weight loss are unsure about what apps to recommend to their patients.

The goal of Project OnTrack is to evaluate the effectiveness of an empirically-supported smartphone app for weight loss and learn about ways in which it could be improved. We are looking for people seeking weight loss to participate in our new smartphone app research study that uses the new and highly popular Weight Watchers (newly rebranded as WW) Freestyle program for 6 weeks. Participants will receive a free WW program subscription, the WW app, and a Fitbit for the duration of the study, and will use a smartphone app to track patterns of sticking to and lapsing from the WW program.
