iPhone Does having multiple fitness/workout apps conflict when writing data into Health.app?

1. I was curious to know if using more than 1 exercise related app will conflict when writing data?
   
   For example I am using Human and Fitport app to monitor my steps, calories, cycling, movement and activity. I also am using the built-in exercise app on my Apple Watch as well, and sometimes I will use Cyclemeter or Runtastic. And I have a withings bluetooth weight scale that is paired with my iPhone as well. So does using all these different apps and devices cause any sort of conflict when writing data into the Health.app?
