Auracle

Auracle is a prediction app for group chats and communities. It lets you turn the stuff you already argue about into quick yes/no predictions in seconds, right where the conversation is happening (starting with iMessage, and shareable to other group spaces). Pick a question, set an end time, and everyone locks in a side.

When the outcome is clear, the group resolves it (not crowd-sourced), and Auracle updates the results automatically with a running leaderboard and a history of who was right. If your group wants, you can also use an optional payout calculator to settle up outside the app.
