First time using this application... Went for 2 hour walk arround my town and beach. From time to time was checking activity on actifit and it went frozen. I had to go to my phone settings and allow actifit aplication to start itaelf. After doing that it went smooth!
Will definitely use this tracking aplication in future night walks as it cought my atention. It would be super interesting to see how much calories were burned.. Maybe there is already inbuild function for that. I dont know but i could not find it.
