Health & Fitness App Users Are Going the Distance with Record-High Engagement

By: Lali Kesiraju, Analytics Manager and Toby Vogels (@tobyvogels), Developer Evangelist


As smartphone users have diversified their app usage, health & fitness apps have become a vital tool to make our lives healthier. In the last three years, health & fitness app usage grew by over 330%. Users are continuously tracking workouts, signing up for classes, and keeping in touch with their general health. We took a closer look at current trends and opportunities for health & fitness app developers.

At Flurry, we reviewed the health & fitness app industry based on app usage (Flurry, now part of Oath, tracks over 1,000,000 apps across all app categories, providing insights into 2.1 billion devices). To investigate current trends, we examined health & fitness categories combining iOS and Android data.


Users are Highly Committed to Their Fitness Apps

Flurry data shows that of active health & fitness app users, 96% are using only one health & fitness app. As seen in our app loyalty matrix, health & fitness apps show the highest retention rates across all categories. This indicates that users are dedicated to their fitness apps once they start using them.

Over 75% of active users open their health & fitness app at least two times a week. Also, there is a remarkably high percentage of Fitness App Addicts: more than 25% of users access their fitness apps more than 10 times a week. As a result, this frequency of usage drives up overall category engagement. For app developers, this presents an attractive opportunity to capitalize on users’ frequent engagement and boost monetization.




Average Weekly Session Frequency


Year-Over-Year Growth is Slowing Down

Since 2014, we have seen massive growth in the health & fitness app category. In just three years, usage grew by over 330%. However, since 2016, growth has slowed down: while we saw a year-over-year growth of 178% from 2014 to 2015, the health & fitness app category only grew by 9% from 2016 to 2017. This correlates with the trends of the overall app industry.

To understand this slowdown in more detail, we segmented the health & fitness market into four sub-categories: Workout & Weight Loss, General Health, Nutrition, and Studios & Fitness Content.




Mobile Health & Fintess App Sessions Grow 9% Year-Over-Year


The largest subcategory, workout & weight loss, shows a significantly slower growth than in the previous year: year-over-year growth is down from 67% in 2015 to 11% in 2016. The other major subcategory, general health, revealed stagnation in the last two years. While nutrition apps declined in the last year, we still see a 49% growth for studio & fitness content apps. The negative trend of nutrition apps is likely influenced by studio & fitness content apps that are offering nutrition content in addition to their core focus.


Track, Set, Go: Workout & Weight Loss Apps Gain Market Share
Workout & weight loss apps account for 73% of all health & fitness app sessions. This represents a substantial gain from a 55% share in 2014. Working out and tracking weight loss are key use cases for health & fitness app users. While general health apps still held a usage share of 41% in 2014, workout & weight loss apps have eaten away large portions of it within the last three years. Wearables, such as fitness bands and smartwatches, have been key growth drivers for that development. According to Kantar Worldpanel ComTech, 15.6% of consumers owned a smartwatch or fitness band in December 2016.




Health & Fitness app usage by category


Apps are no longer optional for Fitness Studios and Health Clubs

Studio & fitness content apps registered the largest percentage increase in the category: Since 2014, studio & fitness content apps grew by over 830%. In 2014, studio & fitness content apps were accountable for 2% of all health & fitness sessions. By 2017, the share increased to 5%. Users continuously declared that they want to arrange their studio visits through a mobile application. This trend makes it crucial for gyms and studios to offer an app that lets their users conveniently schedule their workouts and classes.


Fitness App Usage Correlates with Seasonal Workout Habits

Fitness app usage can be described as highly seasonal: in the last months of a year, fitness app usage declines and hits rock bottom when the holidays approach. December 25th marks the lowest activity with 57% less usage than the most active day of the year, which is August 8. Usage picks up again in January after users have made their New Year’s resolutions and set their fitness goals for the coming year, and it builds up toward the summer, peaking in August. In the last three years, August has always been the most active month by an average of 23% higher usage than the yearly average. From September on, usage decreases again toward the holiday season.




Health & Fitness App Usage Soars on Weekdays


Fitness app activity throughout a week strongly aligns with user workout habits. Users are most motivated to work out from Monday through Wednesday. Once the weekend nears, app usage declines; Saturday marks the lowest activity by 10% fewer sessions than the weekly average.




Health & Fintess App Usage Peaks in the Morning and Evening


Flurry data shows that health & fitness app usage peaks in the morning and evening. People work out before or after heading to work. According to Fitbit, the busiest gym workout times are between 9-11 am and 5-8 pm. Surprisingly, the highest app usage period occurs at around 10 pm. While some people are doing a late-night workout, others might be reviewing their daily activity or planning their next day. For developers, this represents a unique opportunity, as this is a rather unusual peak time for engagement. App developers can leverage the higher engagement for specific marketing and re-engagement tactics.


The future of health & fitness apps and tips for app developers
Health & fitness app users are the most loyal users in the app industry, with high retention rates, engagement, and frequency of usage. A significant share of heavy users with more than ten sessions per week drives constant engagement. That makes this market segment very attractive for app developers. On the other hand, it can also be hard to acquire active users given people typically stick to one fitness application. Fluctuating engagement levels make it crucial for developers to focus on peak times during weekdays in the morning and evening.

Gartner forecasted that there would be over 310 million wearables sold in 2017, which would be an increase of 16.7% to 2016. A study from PwC shows that the number one reason for people purchasing a wearable device is health. This indicates a substantial growth opportunity for health & fitness app developers in the next year.
