productionTimer was designed specifically for the live event and television production industry. Turn most models of iPad or iPhone / iPod Touch into a full-featured countdown clock - perfect for live events! Key Features: - FULLSCREEN countdown on an EXTERNAL DISPLAY via USB-C/Lightning->HDMI or AirPlay - NDI® and SRT output - send the clock over your network to a switcher, multiviewer, remote venue, or playout system - WEB VIEW & REMOTE CONTROL - open the clock in any browser and drive the timer from a separate phone, tablet, or laptop - Bitfocus Companion support - control productionTimer from a Stream Deck or any Companion surface - Send messages downstage - Change text and background colors for normal, warning, and end segments - Smaller cost and footprint than computer or hardware-based timers productionTimer turns an iOS device into a full-screen countdown clock for an external monitor. Take video directly out of the device via the Apple HDMI adapter - run it to a nearby monitor with standard HDMI, send it over Cat-5/5e/6 or fiber, or feed it into a switcher and route it anywhere. Using a switcher, you can even key out the background for a clean countdown over other graphics - perfect for getting attendees back from breaks on time. Prefer to skip the cables? An AirPlay destination like Apple TV works as the external monitor. Need the clock somewhere a cable won't reach? Broadcast it over your network instead - as an NDI source straight into your switcher, or an SRT stream for reliable delivery over longer, less predictable connections. It's also available as a web view, so anyone on the network can pull it up in a browser. Run the show from wherever you are: built-in remote control lets an operator drive the timer from a separate device, and Bitfocus Companion integration puts start, stop, reset, and messaging on your Stream Deck - right inside the control layout you already use. A "warning" changes the clock's background to a user-defined color at a set time - great for cueing talent to wrap up or move to Q&A. Once time is up, the background can change colors again. Need to send a note downstage but don't have switching in place to get it on the confidence monitor? Type a short message and display it on the clock. The countdown shifts up and a large, clear message appears below it - one touch and it's back to normal. Event professionals know the importance of running on time. Need to make up a few minutes? Use "Time-Travel" to run the clock faster than reality - just set the time of day you want it to hit "0" and productionTimer figures out the rest.
