Unfortunately at the current moment with JEFIT, you aren't able to store multiple profiles within the app.
When using the app, you are only able to be logged into one account at a time.
If you want to use another profile with the application, you will need to log out of your current profile that you are using and re-login with the new account that you will like to use.
We are hoping to improve our profile storing in the app in a future update with JEFIT
