You can sync your Endomondo activities through Apple Health and make the most of WeFitter.

All you have to do is go to the general setting, and press Connect with Health.

After you connect your Endomondo account with the Health app, your calories burned and workout distance for all future workouts tracked with the app will be saved automatically to the Health app. You can specify what data to save to Health by giving permission to export:

• Active Energy
• Cycling distance (cycling transport, sport, mountain biking)
• Walking distance+ Running distance
  
  

Once you have linked Endomondo and Apple Health, you simply have to add Apple Health in your WeFitter connections as indicated here.
