Flip the Cube, Start the Clock
Starting a focus session should take one second, not five taps on a phone. This cube uses a gyroscope: turn it so the preset you want faces up, and the countdown starts on its own. No unlocking a screen, no menu — and no phone on the desk to pull you away.
Two Models, Two Working Styles
The TK3 is the full desk version — clock, three alarms, and a choice of silent, vibration, or sound alerts, built for people who live at a desk. The Mini is the small one for a bag or pencil case. Instead of numbers alone, it shows an LED energy bar that fills as time passes, so kids and visual thinkers can read their progress from across the room.
TK3: The Desk Workhorse
Its Pomodoro mode runs the classic rhythm by itself: 25 minutes of work, 5 minutes of break, four rounds in a row. Outside Pomodoro mode you get flip presets of 5, 10, 30, and 60 minutes, custom countdowns from 1 to 99 minutes, and a stopwatch up to 99:59. Set it upright and it is a desk clock showing time, date, and weekday, with three separate daily alarms for your routine.
Mini: Progress You Can See
The Mini's presets are 5, 10, 25, and 50 minutes, and each of the four sides can be reprogrammed to whatever interval you use most. The LED bar fills steadily during the countdown — a glance tells you how far along you are. Flip it upward to pause, downward to reset. A mute switch keeps it silent in libraries and shared offices. At 2 inches across, it disappears into a pocket.

Customer reviews

★★★★★
I asked Gearfinch about the two models because the pictures initially distracted me from their differences. The explanation helped me choose Mini for carrying around.
-
★★★★★
Flipping it to start feels simpler than opening an app. I still have to choose what I'm working on, of course.
-
★★★★★
The Mini's pause action took some practice. I tested it a few times before relying on it during a session I cared about.
-
★★★★★
I found the Mini's custom settings less obvious than the basic flip function. Once I chose the times I wanted, I stopped needing to adjust them often.
-
★★★★★
The cube occasionally started a different interval from the one I thought I'd selected. I'm checking the instructions and my handling before deciding whether there is a fault.
-
★★★★★
The TK3's silent setting suits me during online meetings when I want a private reminder to keep a section brief.
-
★★★★★
Good for short creative exercises. I've used it to sketch several quick ideas instead of spending the whole session refining the first one.
-
★★★★★
I've used the Mini for a few weeks now. It's become familiar enough that starting a session no longer feels like setting up another piece of technology.
-
★★★★★
The TK3 sits where I can see it without moving my laptop windows. That makes it more noticeable than my previous software timer.
-
★★★★★
The TK3's clock is easier to glance at than finding the time on my full-screen work. A small convenience that gets used throughout the day.
-
★★★★★
I bought it mainly to keep the phone out of the process. For that purpose, a separate physical timer has been useful.
-
★★★★★
The TK3's work-and-break cycle has been convenient during long editing mornings. I still pause the routine when a meeting interrupts it.
