A new cell phone based coin is out, and looks promising. As of writing this, there are just over 12,000 users, so you can get in early!
This application is very easy to use and it measures the ambient sound levels near your phone over time, and you are rewarded in coins for that information. This information is then used to draw maps of what sound levels are like around the world.

Once open, click on the circle button on the bottom to start a measurement. As of now, it will allow up to 15 minutes at a time and that rewards you with 15 coins. Of course, this can change.
