What is body doubling?
Body doubling means doing your work alongside another person — physically or virtually. The other person isn't helping with the task. Their presence is the help: it adds a little social accountability, a shared start time, and a quiet sense that "we're both doing this right now." For a lot of people — especially those with ADHD — that's the difference between starting and stalling.
It's why "study with me" videos and virtual coworking have exploded. The format works. The problem is the setup: a video call, a stream, a scheduled room. Most focus apps ignore it entirely and leave you to time your work alone.
Why focusing alone is so hard
A solo timer relies entirely on your own willpower at the exact moment it's weakest — the start. There's no external pull, no one to "show up" for, and nothing stopping you from quietly closing the app. The countdown is honest, but it's also lonely, and lonely is easy to abandon.
The hardest part of deep work is the first ten seconds. Body doubling borrows someone else's momentum to get you through them.
How GlassFocus builds body doubling in
GlassFocus puts body doubling right inside the focus timer with synchronized group sessions:
- Start & share in one tap. Create a session and send a link by message — no account hoops for the basics, no video call to set up.
- Everyone starts together. The timer is server-synchronized, so all participants begin at the same moment, anywhere in the world.
- Focus to the same finish line. You all work until the session ends — a shared start and a shared end, which is exactly what makes body doubling work.
- Add a leaderboard for ongoing accountability. Friends and streak comparisons keep the momentum going between sessions.
No new tool to learn, no separate app for "coworking" — it's just a button in the focus timer you already use.

The bottom line
If you've blamed yourself for never sticking with a focus timer, it may simply be that you were doing it alone. Body doubling is one of the most effective, least-used focus strategies — and GlassFocus is one of the few apps that bakes it right into the timer. Start a session, send the link to a friend, and feel the difference on the very first try. It's free to start.
