About

Debate Clock

Features
Read full description

Debate Clock is a timer built for competitive debate. It runs the whole round — every speech in order, cross-examination, and each team's prep time — so the chair can watch the debate instead of a stopwatch. BUILT-IN FORMATS SDL, JDL, World Schools (WSDC) and British Parliamentary come preloaded with the correct speech order and durations — cross-examination periods, separate prep time for each side, and the protected-time window in which points of information may be offered. CUSTOM FORMATS Build your own: add speeches, set durations, assign them to a team, reorder them, and save as many formats as you need. Start from a built-in template or from a blank list. Rename teams, change their badge and colour, or add new ones. PREP TIMERS Each side gets its own countdown, independent of the speech clock. Pause, resume and reset at any point in the round. BELLS • Interval bell every minute, or a single bell one minute before time • Extra alert 30 seconds before the end • Single or double bell when the speech ends • Triple bell 15 seconds into overtime • Optional bell at the start and end of the POI window, and when a point of information runs out Every bell can be mirrored as a vibration, and sound or vibration can be muted on the spot. MADE FOR A REAL ROUND • A 15-second countdown for points of information, offered only while the speech is inside its POI window • Exclusive timers — starting one clock pauses the others, so two never run at once • Count-up mode if you would rather see time elapsed than time remaining • The screen stays awake while a timer is running • Swipe between speeches on a phone; on a tablet the full speech list and both prep timers sit beside the clock • Keyboard shortcuts: space to start and pause, arrow keys to change speech • English and Slovak, matched to your device language No account, no ads, no tracking. Everything is stored on your device and the app works fully offline.
