Features
Display your status
Stop others from interrupting your deep focus. The display shows you’re busy and when you’ll be free again.
Automatic status
BUSY Bar integrates with desktop software and automatically activates when you’re on a call, live on stream, recording audio, or when a certain program is active.
Interval focus timer
BUSY Bar is an advanced productivity timer inspired by the Pomodoro technique, which divides work into short intervals — 25‑minute work sessions followed by 5‑minute breaks.
Block distractions
BUSY Bar can automatically mute notifications on your phone and PC when BUSY mode is activated. It helps you stay focused by blocking distractions as you work.
Mute all devices
BUSY Bar integrates with the free cloud-based BUSY App infrastructure. Block distractions across all platforms simultaneously, so nothing pulls you away while you’re focused. BUSY App works on your computer, phone, and smartwatch.
Smart home integration
Make your smart home react when you’re busy: pause music, turn on lights, and lock the door with just one button. BUSY Bar supports Matter®
Remote control
Control BUSY Bar remotely over the internet. Place it on the wall or door and use the desktop app to automatically activate the BUSY status when you’re on calls.
Developer-friendly
Right out of the box, BUSY Bar comes with an open API, ready for integration into your project.

Connect to your smart home system for seamless automation

Open-source firmware
BUSY Bar runs on fully open firmware — the exact code we ship, published on GitHub under GPLv2.
Built to be extended. Every mode and service is open C, using FBT and a documented SDK to build and load custom apps alongside the built-ins.
No lock-in, nothing hidden. The whole firmware is auditable, buildable from source, and free to fork.
