The effectiveness of exercise apps in terms of the functions and time to achieve weight goals are not well documented. The aim of this study is to determine whether using an app is beneficial to achieving an individual’s weight goals. In a quasi-experimental design, 45 participants from Andrews University and the community were enrolled in the study. Measurements were taken from two groups; the treatment group used the Andreasen Wellness Center app and control group had no app. Weight and height for Body Mass Index (BMI) was taken at baseline-initial visit and after four weeks. The effect of using the app was evaluated using a paired t-test to compare the mean BMI before and after four weeks of exercise. The difference between the groups was assessed using an independent t-test. The treatment group lost weight significantly for those who intended to lose weight. However, the difference in change between groups of app user and no app user did not reach significance. Small sample size and shorter time was the major limitation of this study. Larger sample size with longer follow up period should be considered for future studies.
