A body doubling app with the camera switched off
Shared focus rooms, one timer everyone can see, and no video call. The accountability of working next to someone, without the performance.

Why working near someone makes starting easier
Body doubling is the simplest productivity technique there is: another person is present while you work, and the task you have been circling for two hours suddenly begins. Nothing is enforced. Nobody checks on you. The presence itself carries the weight.
The problem with the video-call version
Most body doubling products put you on camera with a stranger and ask you to state your goals out loud. For plenty of people that is the good part. For plenty of others it is the exact reason they never book a second session: a webcam is a performance, and performing is the opposite of focusing.
How Kosmonia rooms work
- One shared countdown. Everyone in the room runs the same timer, so breaks land together.
- A live presence count. You can see how many people are focusing right now. That is the whole social signal, and it is enough.
- No camera, no microphone. Nothing to set up, nothing to tidy behind you.
- No booking. Rooms are running. You drop in when you are ready instead of scheduling a slot 40 minutes from now.
- Sound comes with it. Rain, cafe, forest, brown noise, lo-fi. Mix a couple of layers and save the mix.
What it costs
Camera-based co-working services generally sit between $8 and $40 a month. Kosmonia's free tier includes focus sessions and core sounds, and the paid tiers cost less than a sound-only subscription while including the timer, the rooms and everything else.
If you have ADHD
Task initiation, not task execution, is usually the wall. A room that is already running removes the two steps that stop people: deciding to start, and setting something up first. Open the page, join, begin.
Try it without an account
The free focus timer runs in the browser with no signup, so you can feel the session length and the sound before deciding whether the rooms are for you.
Frequently asked questions
- What is a body doubling app?
- An app that lets you work alongside other people in a shared session so that starting and staying on task gets easier. Kosmonia does it with a shared timer and a live participant count, with no camera.
- Do I have to be on camera?
- No. Kosmonia's focus rooms are camera-free by design. You see how many people are focusing and the same countdown everyone else sees, and nothing points at your face.
- How is this different from Focusmate?
- Focusmate matches you one-to-one on video and requires you to stay on camera. Kosmonia uses camera-free rooms with a shared timer, and the focus timer, sound library and progression come in the same app.
- Is body doubling useful for ADHD?
- Many people with ADHD find that another person's presence makes task initiation dramatically easier. It is a widely used strategy, though it is a coping tool rather than a treatment.
- Is it free?
- Yes. Free covers focus sessions and core sounds. Paid tiers add unlimited rooms, advanced sound mixing and cloud sync.
