KeyTimer 2.0.1 improves Control Screen reliability on Intel Macs, keeping cue messages, line weight, and key mode changes in sync with the live output. KeyTimer is a chroma key countdown timer designed for presenters, speakers, and production teams in broadcast, livestream, recording, and stage environments. Connect your Mac to a video switcher or return monitor over HDMI. Key out a green, blue, or luma background to overlay a clean visual timer for talent, guests, or speakers. KeyTimer can show: - A countdown timer - The current clock - Cue text for presenters - Chroma key backgrounds for green, blue, and luma key workflows KeyTimer is silent by design, so it will not play alarm sounds during a live program or recording. Use the free version for timers up to 15 minutes. KeyTimer Full Version unlocks timers longer than 15 minutes with a one-time in-app purchase. Built for: - Broadcast studios - Livestream production - Recording sessions - Webinars and lectures - Events, talks, and stage management - Any setup that needs a clean visual timer on an external monitor Simple, quiet, and made for production rooms where every second matters.
