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).

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