Don't waste your time. It's another as hungry app. The geomining is not worth it you have to have the app open all the time, have to complete puzzles to reset blocks. The surveys are a joke I wasted an hour trying to do five and each time after saying they found ones that match my profile I did not qualify for based on my answers. I don't have time to babysit my phone. If it won't run in the background then don't make the app like it is. Yeah we all want a buck at the end of the day I know.
