Tally Ho

Tally Ho turns any Stream Deck key into a shared, synced indicator between two or more people. Press a key and every other key with the same ID lights up to match — instantly, across every Stream Deck and mobile device connected to your computer.

Built for on-air tally, but just as useful for any quick binary signal between people who can't easily talk mid-show: a musician flagging the sound engineer to raise or lower a specific channel, a stage manager cueing a performer, or a simple "standing by / go" between two stations.

Features:

Toggle, momentary, or exclusive (radio-button) button modes

Fully customizable colors and label text per key

Group support for exclusive switching between multiple sources

Instant sync across unlimited Stream Decks and mobile devices on the same computer

Example uses:

On-air / live tally for cameras or sources

A performer signaling "raise guitar" or "lower piano" to an audio engineer, with the engineer's deck lighting up to match

Cueing between backstage and front-of-house

Any simple status flag shared between two people at different Stream Decks

Use it to keep track of staff or availability.
