Countdown Presets Timer Cube, for Study Sessions

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.
