Smiles.. I had the same problem when I started the usage of the app. I would og for long hours and won't get the steps I wanted so I develop a trick to help out..

Firstly

• never close the application when exercising
• remove all phone locks from the phone
• lastly check if the app is still tracking ur steps every hour or two.

Thats all I know. I also make use of the app, you could check out my blog to see what I have done so Far
