Whistlr — The referee's smart game timer Whistlr turns your Apple Watch into a purpose-built match clock for anyone officiating a sport played in timed periods. No more juggling a stopwatch and a phone — set up your game once, then run it from your wrist. Built for officials, coaches, and referees of every sport If it's played in periods, Whistlr can time it. Soccer, rugby, basketball, ice hockey, field hockey, American football, Australian football, cricket, lacrosse, handball, volleyball, water polo— and anything else with a clock. Two timers at once Every period shows elapsed time large and time remaining small, so you always know exactly where you are in the half. A subtle haptic taps you on the wrist when the period overruns— no more glancing down for the buzzer. Configure once, remember forever • 2, 3, or 4 periods — auto-labelled as halves, thirds, or quarters • Period length: 5 to 50 minutes • Half time / break length: 1 to 20 minutes, with optional different lengths per break (ideal for basketball-style short quarter breaks and a longer halftime) • Extra time: up to 4 additional periods of 5–30 minutes each • Stop Clock: double-tap to pause the period when play is dead (great for ice hockey and basketball) All settings persist between games — the next time you open Whistlr, everything is exactly as you left it.
