How do I connect a Bluetooth speaker?: On iPhone, tap the speaker icon in the top-right corner to pick your audio output. On Apple Watch, tap "Connect Speaker" in the settings section before starting a countdown.
Can I use the Watch without my iPhone?: Yes. The Watch app works standalone with haptics and visual countdown. For audio through a speaker, pair a Bluetooth speaker directly to your Watch, or toggle "iPhone Speaker" to use your phone as the sound system.
What does the Timer setting do?: Timer adds a lead-in before the crowd countdown starts. Set it to "—" for an instant countdown, or 15/30 seconds for a shot-clock feel with ambient crowd noise building up to the count.
The audio cuts off early or the buzzer doesn't play.: Make sure the audio file hasn't been accidentally removed from the app bundle. If you're on Apple Watch Series 9 or earlier, the built-in speaker doesn't support media playback — use a Bluetooth speaker or the iPhone remote mode instead.
