Samsung pear/sport tracker problem

Hey guys!!
I love to speedskate and when I turn on the pear app it randomly hold on the activity, all what I need is to track via gps the time and the km I have done, any suggestion for other app?

Snapchat Score Tracker?

Is there any way to monitor my Snapchat score? Something that monitors it every minute or whenever it updates, and then records it then displays like a graph based on day/month/year?
