Based in London Fin devices Known for Flipper Zero toolused by hackers and tinkerers to access various radios equipped with Bluetooth, RFID, NFC and sub-1GHz transceiver. Today, the company has taken a different direction and launched a productivity-focused tool called Busy Bar, which helps you set timers, block apps, and display custom messages and widgets on the LED display.
Flipper Devices announced the device last year, and now it will put it on open sale next month. Busy Bar looks like a table clock with many knobs and buttons. On the front, it has a 72 x 16 LED matrix display with up to 400 nits of brightness, support for 16 million colors, and a sensor for automatic brightness adjustment.
On the back there is a monochrome display to display status, timer, battery and connectivity indicators. This allows you to see the information if the screen is facing the other side. Moreover, there is a small speaker on the side to play custom sounds and notifications.

On the top, there’s a mode selector switch, a start/stop button, an indicator, and a scroll wheel for navigating menus and setting the time. The device has Wi-Fi, Bluetooth, and USB connectivity options.
The Busy Bar has a 3,250 mAh battery, which can last for up to eight hours of active status time and up to two weeks of standby time. The company said that using a 15-watt adapter, users can fully charge the device within an hour.
The idea behind the device is that you can set a message to signal others (and yourself) when you’re performing a task. This is useful in a work-from-home setup where you may have other people at home. You can also set Pomodoro style timers for productivity blocks so you can focus on finishing tasks.
Flipper Devices releases apps for iOS, Android, and macOS, with support planned for a Windows app. Users can block specific apps using different types of timers on iOS and Android. Additionally, there is microphone integration with macOS, through which the device displays an “On Call” status on the screen and mutes notifications when you join meetings, start recording, or broadcast.

The Busy Bar is also Matter certified, meaning it can work with your existing smart home setup across Amazon, Apple, and Google-based smart home ecosystems. This means that users can trigger smart home automations based on the status of the bar.
The company has made the device convenient for developers to customize it using open firmware. They can use HTTP API, MQTT, and official Python and TypeScript libraries to create widgets and colors. Users can also control Busy Bar online through its cloud API.
Users can join the waiting list on the Busy Bar website, and the first 3,000 users will be able to purchase the device for $199. All other users will have to shell out $249 for the device. Shipping and sales will start from July 14 to the US, EU, UK and Canada. The company also plans to release accessories, including wall mounts, screen protectors, and custom switches.
