Flip it. That's the whole setup.
Four sides, four blocks of time. Turn the side you want face-up and it starts. Turn it back and it pauses. Your phone stays in the other room.
Each side is a decision you never have to make again
- 5 min · Reset — the side for starting. Clear the desk, open the doc. Momentum, not effort.
- 10 min · Small thing — the email, the form, the call you keep pushing. Ten minutes and it's gone.
- 30 min · Focus — one task, one block. Long enough to get somewhere, short enough to start.
- 60 min · Deep work — for the thing you've been avoiding. Flip it and the hour is already spoken for.
Need a different length? Set any side to a custom time from 1 to 99 minutes. Most people set 14:24 — one percent of a day — and give it to the hard task.
Why a flip, not an app
Every phone timer costs you an unlock, a swipe, and whatever notification was waiting behind it. Tetrafold removes the moment where focus usually dies. There is no screen to wake, no menu to find, no number to type. The gesture is the setting.
- Zero-friction start — flip a side face-up. It's already counting.
- Pause without losing the block — turn it to a blank side; flip again to resume.
- A display that isn't a screen — large LED digits show the minutes and nothing else. No notifications, no temptation.
- Built for ADHD desks, useful on every desk — designed with time-blindness in mind: readable from across the room.
- Quiet by default — soft chime, loud chime, vibration, or silence. You choose once.

What it is, and isn't
It is a physical timer you start by turning it over. It is not an app, a tracker, or a subscription. It won't buzz you with notifications and it won't sync to anything. If you want your phone to be part of the system, this isn't the tool. If you want your phone in the other room, it is.
Sixty days to decide. If it isn't earning its spot on your desk, send it back.
QUESTIONS PEOPLE ACTUALLY ASK
Before you buy
Does it need an app?
Does it need an app?
No. There is nothing to download, pair, or sign into. You set each side once on the cube itself.
How do I pause?
How do I pause?
Turn the cube so a blank edge faces up. Flip the same side back up and it resumes from where you left it.
Will it help with ADHD?
Will it help with ADHD?
We designed it around the two things people with ADHD tell us break every other timer: starting takes too many steps, and time is invisible. Tetrafold starts with one motion and shows the countdown from across the room. We don't make medical claims — we make the starting part easier.
Is the chime loud?
Is the chime loud?
You choose: silent, vibration only, a soft chime, or a loud one. Set it once on the base.
What if it doesn't work for me?
What if it doesn't work for me?
