Focus and productivity apps abound, all to help you stave off the many distractions coming from your phone. Or the annoying people at your open-office desk. Digital well-being tools can silence notifications, limit apps like TikTok and Instagram, and help you focus on the task at hand. But you can also turn them off very easily as soon as you feel like you haven’t endlessly scrolled enough.

This is where Flipper’s Busy Bar comes in, a hardware clock with an LED screen that doubles as a clock and a dedicated timer. Slap the big button in the middle, and the screen displays a bright red “BUSY” sign or another message that lets the people around you know you’re, well, busy. (Maybe try “GO AWAY” or “GET OUT OF MY ROOM, MOM.”) The bar goes on sale today and costs $249.

“How do you let people know politely, yet firmly, that you don’t want to be disturbed?” says Callum Tennent, a creative writer at Flipper. “We decided the politest way to do it was a massive red light on your desk.”

Flipper Devices made the Flipper Zero, a $200 portable hacking tool that got big on TikTok in 2022 for using a Tamagotchi-esque dolphin character to detect wireless frequencies and potentially break RFID-controlled locks. It was a device that raised a variety of security concerns. Canada proposed a ban on the device out of fear that it might enable car thefts. In 2023, the US Customs and Border Protection seized 15,000 Flipper Zero devices, then ultimately released them. Flipper is currently working on another model, the Flipper One, that has even more advanced capabilities.

In between those more controversial devices comes the Busy Bar. The bar also works with the separate Busy app, yet another one of those productivity and focus tools living on your phone. What it doesn’t have is the capability of hacking anything. “It’s being made by us here at Flipper, but there’s no real connection to them,” Tennent says. “They’re totally disconnected products.”

Fundamentally, the Busy Bar is a pricey “On Air” light. It offers many of the same productivity capabilities that are likely already baked into your phone’s operating system—like blocking notifications on your phone. But Flipper is making the case that—much like the Brick, a hardware gadget you tap to block access to certain apps—having a hardware option to shut off the distractions around you is meaningfully different than just trying to use software productivity tools on your device.
