A biometric data app is helping the services monitor the health of sailors and airmen stuck at home. Even when the gyms are closed, sailors and airmen have to stay fit, which can be a big challenge both for reservists who may not be used to staying at a specific fitness level to joint tactical air controllers with Air Force Special Operations. The Air Force is eight months into a proof-of-concept trial with CoachMePlus, an online health tracker and fitness coaching service that can work with other devices, or by itself, to help people reach fitness goals. Individuals can use the app to designate specific goals (or more generic ones) and the app then monitors their progress and offers feedback to improve performance, like a regular coach. Unlike some other fitness trackers, the service can be tailored to different populations under the same umbrella. It can incorporate nutrition and other data for a more complete picture and also integrate data from personal wearable fitness devices like FitBits to provide a better and more predictive picture of individual health.
