Everyday

One glance is enough.

At home, at the office or in a team: the Dot shows at a glance whether now is a good moment – and answers the question before anyone asks.

FREE. · At the door

Come on in.

Green at the door: you are available. Anyone passing by sees it at once – no need to knock.

What FREE. means

How it works

Three colours. One clear rule.

Everyone understands a traffic light – children, colleagues, visitors. You set the status with a tap on your iPhone, Apple Watch or Mac. On the Mac it can switch automatically. Android is in development.

FREE.

Come on in.

You are available.

FREE.

Green means: I am available. Now is a good moment for a question, a visit or a quick chat.

  • Door open for family or team
  • A break between two meetings

BUSY.

Please knock.

You are briefly occupied.

BUSY.

Amber means: I am busy. If it is important, knock – otherwise please come back a little later.

  • A phone call or a focused task
  • Automatic on the Mac as soon as the microphone is on

FOCUS.

Do not disturb.

You need quiet right now.

FOCUS.

Red means: I am concentrating or on a call. Please do not interrupt right now.

  • Video call, recording, exam
  • Automatic on the Mac as soon as the camera is on
Why

A brief interruption. A long way back.

A brief interruption at the wrong moment – and your focus is gone. On a call, working from home, while studying. The problem is rarely the interruption itself; it is the moment. That is why BusyDot® helps you avoid the interruption before it happens.

about 25 minutes

pass on average before someone is back at their original task after an interruption – usually with two other activities in between.

The Mac

The Mac switches by itself.

The Mac app detects whether the microphone or camera is in use and sets the status: microphone on means BUSY. Camera on means FOCUS.

  • Automatic instead of tappingThe Dot switches as soon as a call starts, and back again when it ends.
  • Lives in the menu barA dot in your status colour; one click for status, timer and power switch.
  • Never listens inIt only reads whether the camera or microphone is running – never picture or sound.
How the detection works

The Mac app uses the same signal macOS uses to show the green and orange dot in the menu bar. It does not open any audio or video stream, which is why there is no permission prompt for the microphone.

The camera takes priority over the microphone: anyone walking in while video is running ends up in a call uninvited. The automation can be paused at any time; a status you set by hand then stays put.

FREE.
Come on in.

Questions

Briefly explained.

Not yet. BusyDot® is in development. By joining the list you will be among the first to hear when it is ready – no obligation, no purchase.

FREE. (green): come on in, I am available. BUSY. (amber): please knock, I am briefly occupied. FOCUS. (red): do not disturb, I am concentrating.

With a tap in the app on your iPhone, Apple Watch or Mac – also via widgets and the Live Activity. All devices stay in sync. On the Mac it can switch automatically. On the Dot itself, a tap on the centre moves to the next status.

The Mac app detects system-wide whether the microphone or camera is in use – using the same signal macOS uses to show the green and orange dot in the menu bar. Microphone on means BUSY., camera on means FOCUS. Only the device state is read, never picture or sound. The automation can be paused or switched off at any time.

A thin metal ring is attached to a door, wall or desk; the Dot holds on it by magnet. To charge it, you take it off.

How the ring will be attached in the final product and how firmly the Dot holds are things we are currently testing on the first samples.

Via USB-C or wirelessly on a Qi charging pad. Take the Dot off the ring to charge it. The app and the Dot itself show the battery level. We are currently measuring how long a charge lasts on the first samples.

iPhone, Apple Watch and Mac – with widgets, a Live Activity on the Lock Screen and in the Dynamic Island, and a complication for the watch face. The app is available in English and German. An Android app is in development.

For the launch list we store your name and email address – and, for “For my team”, also company and quantity – with the email service Brevo, and only after you confirm. The app needs no account; status and settings stay on your device.

Details: privacy policy for the website and privacy policy for the app.

Yes. Choose “For my team” when you sign up. For practices, care, restaurants, schools and offices there are dedicated scenarios under For business.
