Round 1's draw has yet to be released

Still timing debates with the stopwatch app?

Using an app designed for debate timekeeping makes speaking and adjudicating easier! Check out Timekept (iPhone/iPad) or Debatekeeper (Android).

Our Organisation

Tabbycat is supported by the Tabbycat Debate Association, a non-profit for advancing open debate technology.
