About

GrassKarma is a hyper-local lawn care sharing platform. Streets organize into groups. Someone in the group owns a mower and offers to cut lawns for neighbours. Karma points track who's contributing and who's receiving.

Each street group is geocoded to a real address range. Members join by entering their street address — the platform matches them to the nearest group or creates a new one. Reviews and karma scores build trust within the group.

Built on the premise that most suburban streets have 3-4 lawnmowers for 20+ houses. One shared mower, maintained by the group, cuts everyone's lawn on rotation. The app just coordinates who, when, and tracks the karma.

GrassKarma is a Pro app on ProAppStore. It uses the ProAppStore SDK for authentication, real-time features, and data storage. The source code is available on GitHub.
