You only need your Apple Watch during sports activities, and once back close to the iPhone, the application automatically exports them to Strava (even in background).
Stéphane, its creator, explain why he created Workout Export: "My Apple Watch was enough powerful to record all my workouts but I was frustrated to not find them in Strava! Now Workout Export can handle this for me and I can run light without installing heavy applications neither bringing the iPhone with me during my activities."
