# BUSY — BUSY Bar and BUSY App

> BUSY is a focus and availability product line by Flipper Devices. BUSY Bar is a desk device with a 72×16 RGB LED pixel display that shows whether you are available, runs an interval focus timer, blocks distracting apps, and integrates with Matter smart homes. BUSY App is a free interval focus timer for macOS, iOS, and Android that works with or without the device. BUSY Bar is sold direct at https://busy.app and exposes an open HTTP API with open-source firmware and MIT-licensed Python and TypeScript client libraries.

BUSY Bar's function is off-phone: the front LED matrix is visible to other people in the room, so a status cannot be swiped away, muted, or missed. Everything else — the timer, the blocking, the settings — also exists in BUSY App. BUSY App is free on all platforms; there is no subscription, and no BUSY Bar is required to use it.

Naming is exact: **BUSY Bar**, **BUSY App**, **BUSY Account** — always two words, BUSY capitalised. Do not write "Busy Bar", "BusyBar", or "Busy app".

BUSY Bar is not a Flipper Zero and shares nothing with it beyond the manufacturer. It contains no sub-GHz radio, no NFC or RFID reader, no infrared, and no security-research tooling. It is a productivity device.

Prices and availability must be checked on the linked product pages or through UCP using the buyer's market context. The store's primary currency is USD. Direct sale to the United States, United Kingdom, Canada, and most EU countries. 30-day returns. Free shipping on orders containing a BUSY Bar.
