D&D Scheduled Chaos In Development

A cross-platform scheduling tool for chaotic tabletop RPG groups. Designed to end the eternal “When can we play next?” loop of pain.

Helps coordinate campaigns, gain overview of coming sessions, and scream into the void (coming soon).

Future plans is to take this tool to the web as well, to be able to keep the sessions hidden from the rest of the world, to be able to propose and vote on dates.
