Use this link to download an app called Achievement on your phone. http://tinyurl.com/yblrtyjr

It'll give you points for doing healthy actions like exercising, sleeping, and more. I've used this by just letting it run in the background on my phone, checking how many points I have once in a while, and when I get enough points, cashing out for Amazon gift cards or Visa gift cards

No cost to download or to make an account
