BUSY Bar LED Display
The most effective productivity tool might not be another app. It might be a small LED display that tells everyone around you to leave you alone.
Busy Bar is a 72 by 16 pixel RGB LED matrix that sits on your desk or clips to the top of your monitor and shows your current status: available, busy, in a meeting, or do not disturb. That sounds simple because it is. The value comes from the automation behind it. Connect it to Slack, Microsoft Teams, Zoom, or Google Calendar and the status updates itself as your day unfolds. Start a video call and it switches to On Call. Enter a calendar block and it shows Busy with a countdown timer. Finish the meeting and it reverts without you touching anything.
The distraction blocking is where it goes further than a status light. Activate focus mode and Busy Bar can mute notifications on your phone and computer simultaneously through the companion app. It blocks specific apps entirely during focus sessions, including Instagram and TikTok, so you cannot even open them until the timer runs out. An optional Hardcore mode locks selected apps for the entire session with no way to bypass it short of a full phone reset. A built in Pomodoro timer structures work into focused intervals with breaks.
Smart home integration runs through the Matter protocol, connecting to Apple Home and Google Home. Start a focus session and your smart home can pause music, adjust lighting, or lock a door automatically. Home Assistant integration via HTTP API adds deeper customization for anyone running an open source setup. The device works as both a trigger and an output, meaning your smart home can also push notifications to the Busy Bar, like alerting you when the washing machine finishes.
The hardware is built for desk use. A monochrome OLED back screen mirrors the main display so you can see your own status when the bar faces outward. Physical controls include a large start and pause button, a five position mode selector, a scroll wheel for setting timers, and a back button. A Kailh Choc mechanical switch handles the main input. 3,250 mAh battery delivers 8 hours of active status. USB C for charging and PC connection. Wi Fi 6 and Bluetooth 5.4 handle wireless connectivity.
For developers, Busy Bar ships with an open HTTP API, SDK libraries for Python and TypeScript, MQTT support, and no vendor lock in. Connect via USB virtual LAN, local Wi Fi, or cloud. Self hosted cloud control is available for anyone who wants to keep data off external servers.
The apps section adds a clock, weather, social media stats for YouTube, Instagram, and TikTok, and support for third party user applications. Custom LED animations, countdown timers, and status messages are configurable for any workflow.
It is one of those products that makes you wonder why it did not exist sooner. We have all taped notes to doors and sent Slack messages asking for ten minutes. Busy Bar turns that into something automatic, visible, and integrated into the tools you already use.
