The Geisinger Health System has released a new iPhone app to assist patients to determine how much weight they would lose from bariatric surgery. The free app, called “Get-2-Goal” and available at the App Store, allows the patient to enter their age, weight and height and calculate personalized expected weight loss based on national averages of persons with similar characteristics. Post-surgery, the app allows the patient to track weight loss over time, generate motivational content, and email their physician. Christopher Still, D.O., Director of the Geisinger Obesity Institute stated, “The most useful function of this app is that it ensures patients are fully informed and have realistic expectations after their procedure.” The app was developed in collaboration with Bucknell University.
