Fitbit
There are plenty of different options to choose from, whether you're looking to track your running or your diet. And according to mobile analytics company Flurry, these apps are getting a whole lot of usage.
Between December 2013 and June 2014, health and fitness apps grew 62% in usage, compared to apps overall which grew just 33%.
To get a better idea of which of these apps are topping the rest, we decided to rank them based on information from research company AppData.
The company calculates app download estimates based on the frequency and quantity of an app's ratings. When applicable, they also calculate how many users logged in to an app via Facebook and an estimated iOS revenue based on ranking, in-app purchases, and the cost of the app itself.
