If you're into surveys, chances are you will also get quite a number of invitations or ads from survey sites, especially in Facebook. And that is how I was able to learn about Achievement.
Achievement, like any other survey sites, has surveys that will make you earn. But they also have other ways for you to start earning.
Aside from surveys which concerns most about your health, you are also able to connect some health apps that monitors your daily health routines. To sign up, just go directly to their website and register, and once done, download the app from the Playstore or Appstore.
The app allows you to earn a quick $10 and the payment can be processed thru your Paypal account.
Unfortunately, this service works only for US citizens since they will be asking for your valid US address.
