Spory

Spory lets you workout with your friends. Add your friends in Spory and compare your workout with them.

How it works:
Pick your gym -> Enable location services for Spory -> Search for your friend(s) -> Add them as a friend -> **your friend accepts your friend request** -> Challenge them to workout X times/week -> **friend accepts your challenge** -> Go to gym.

Once you enable location services, your visits to the gym are automatically tracked.

Heads up: Won't work well if your device is on low power mode :(
