The Customer is a US company that provides healthcare and sport organizations as well as military forces with superior information and research on the population’s physical well-being and effective training techniques.


The End Customer needed an app that would gather PGHD and analyze the person's physical state using different heart rate monitors, such as Wahoo Fitness, 60beat BLUE Heart Rate and Zephyr.


ScienceSoft’s medical iPhone app development team designed and created a native iOS app that offers a quantitative assessment of users’ physical fitness. The evaluation relies on the Heart Rate Variability (HRV), which is recognized as a reliable indicator of fitness condition. The fitness assessment is built upon a simple 3-4 minute lying-to-standing test plus Valsalva maneuver with deep breathing. 

To start a test session, the user needs to put on the heart monitor and turn on the app on his iOS device. Then, the app will ask to perform a series of easy actions. The heart beat data will be gathered and transferred from the monitor to the app. The latter will show the results on a handy, three-colored chart, where the blue stands for athletic qualities, the green defines the person’s average performance, and the red indicates low physical abilities.

Therefore, a physician, trainer or medical officer is able to measure the patient’s response to exercise stress and act appropriately.


The Customer received an iOS app that supports all the required heart monitor devices. Healthcare and military organizations now use it to help patients improve their well-being. The app is capable of:

  • Evaluating the initial fitness level
  • Monitoring the training program progress
  • Identifying any changes in fitness condition
  • Interpreting the test results immediately
