Adherence

Using a mobile app to self-monitor physical activity increases the frequency of exercise recording and total intentional energy expenditure, leading to greater weight loss and lower BMI compared to not using a PA app.

If you are trying to lose weight, use a mobile app to track your exercise. This study suggests that using an app helps you exercise more often and burn more calories intentionally compared to not using an app or using other methods. The key is the ease of tracking, which likely improves adherence.

PA app users self-monitored exercise more frequently over the 6-month study (2.6±0.5 days/week) and reported greater intentional PA (196.4±45.9 kcal/day) than non-app users (1.2±0.5 days/week PA self-monitoring, p<0.01; 100.9±45.1 kcal/day intentional PA, p=0.02). PA app users also had a significantly lower BMI at 6 months (31.5±0.5 kg/m2) than non-users (32.5±0.5 kg/m2; p=0.02).
