Harrier Central is the free app for Hash House Harriers everywhere. Find a run around the corner or across the globe, RSVP in a tap, and keep every run you have ever done stored safely in the cloud. PackTrack puts the whole pack on one live map. Drop trail marks as you go, find everyone with the radar, find your way back with the lost compass, and snap photos that land on the map where you took them. Replay any run afterwards, or share a link so friends and family can follow along in any browser. Put it on the big screen at the On-Inn with Trail TV. There is a chat for every run and every kennel you follow, an interactive songbook that switches the whole pack to the same song, and a Hash Flash gallery where the run's photos live. For mismanagement there is plenty to make the job lighter: check the pack in even when there's no network available, take payments, charge memberships and sell haberdashery, manage runs and hares, and set who can do what for each kennel. Built by hashers, for hashers. On-On! Opee and Tuna Melt London H3, City H3 (London, England)
