The SnapCrap app was created to report human waste on San Francisco streets, but it is no longer available for download. The city's official SF 311 app is the current way to report these issues, though it may be less direct.

One of the wealthiest cities in the world has homeless people relieving themselves on sidewalks, between parked cars and in planters boxes - pedestrians must two-step over so much human waste.

The city’s downloadable app is logging in about 24,000 to 25,000 human poop piles a year.
