Set Theory Clock (BerlinClock) vs productionTimer

The Berlin Clock consists of 24 lamps arranged in 4 rows.  The top two rows (red) represent the hours, and the bottom two rows (yellow) represent the minutes. Additionally, a circular yellow lamp at the top flashes every 2 seconds. In the top rows of each color, each lamp represents 5 hours or 5 minutes, respectively, while in the bottom rows, each represents 1 hour or 1 minute. The lamps light up from left to right and from bottom to top. Once a row is full, all lamps turn off and another lamp lights up in the row above it.

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.
