Avalanche Messenger

Avalanche is the best organizing platform for in-person coordination: conferences, canvassing, local organizing, and anything else. Avalanche starts with encrypted messaging as the base, and atop that enables well-integrated organizing tools: group auto- and self-join, browse attendees, team assignments and subgroups, volunteer management, Q&A bots, and whatever else you can dream, all integrated into one mobile app that is as easy to use as texting.
