There are thousands of exercise apps that cover a wide range of physical activities from walking and running to exercise classes and apps for personal trainers. Increasingly many fitness apps can sync with a wearable device such as fitness bands and smart watches.

Types of exercise apps

Physical activity apps can be categorised into five groups according to their main focus:1

  • workout apps that demonstrate various exercises
  • tracking of movement apps that map running, walking or cycling routes
  • running programmes that have pre-specified goals reached by gradual small increases in run-to-walk ratio
  • pedometer-based apps that count steps
  • interval timers that time work and rest periods.

Can smartphone apps increase physical activity?

To answer that question, we need to look at the evidence provided by reliable studies, such as randomised controlled trials.   An analysis of 9 such trials that used a smartphone app as the key intervention to increase physical activity found that these apps had a modest positive influence on physical activity.2 Physical activity was measured as either moderate-to-vigorous physical activity minutes or steps. The analysis found that, in particular, smartphone apps have a significant positive effect on physical activity when used over a short-term period (ie, less than 3 months) and where apps target physical activity alone, rather than physical activity in combination with other health behaviors. The authors conclude that future research is needed to understand more about the effect of the apps over time, and to investigate strategies to sustain the effects of using the apps over time.

Deciding on suitable apps - help me choose

As there are so many apps for physical activity and exercise, finding a fitness app to meet your needs can be challenging. It depends largely on your preferred type of exercise and other qualities you want your app to have. The inclusion of behaviour change techniques in the app features may be helpful. For example, does the app have the following features:3

  • goal setting: prompt you to set goals and plan your exercises 
  • monitoring: allow you to monitor your progress
  • feedback: provide feedback on your performance
  • rewards: offer rewards when you achieve your goal
  • social support: have an online community or other means of social support. 

Alternatively, when deciding on a fitness app, you may find the use of the fitness app scoring instrument [PDF, 172 KB] useful to compare and  contrast features.4

  • This tool is based on the American College of Sports Medicine (ACSM) recommended exercise prescription, which consists of three main components: aerobic exercise, strength and resistance, and flexibility.
  •  It provides a structured way of assessing fitness apps and has notes or qualifiers to help you along.
