              When you plog, you pick up trash as you go about your daily life... jogging, hiking, or simply walking down the street. Ploggers help keep our neighborhoods, parks, and oceans clean.

              Plogalong helps you track your plogging history and see who else is plogging nearby. Stay motivated by earning badges and plogging minutes, or sharing your plogs on social media.
