The gravity timer cube is a smart time management device with an LED display, designed for learning, work, the kitchen, or sports. Simply flip the cube to the desired side and the timer will automatically start counting down. Three models are available – YS, F4, and F6 – with different sizes, features, and sound settings, so everyone can find the perfect option for their needs.
The gravity timer cube is perfect for students, remote workers, or those learning the Pomodoro technique. It's also useful in the kitchen while cooking, during workouts, or when reading, as it allows you to track time without distractions. Simply select your desired time interval by flipping the cube to the correct side – the timer will automatically start counting down. Its quiet operation makes it suitable for use in offices, libraries, or at night, without disturbing others.
Q: How does the gravity sensor work?
Each side of the cube corresponds to a different time interval, such as 5, 10, 25, or 45 minutes. When you flip the cube to the desired side, the timer automatically starts counting down without any extra buttons.
Question: Can I use the timer without sound?
Yes, all models have a silent mode – in the F4 and F6 versions, you can choose between an alarm, vibration, or silence, so the timer won't disturb your work, studies, or sleep.
Q: How long does the battery last without charging?
The battery life of the F6 model is approximately 6-8 months on a single charge. All models have a 500mAh rechargeable lithium battery that can be charged with a USB cable.
The gravity timer cube is a convenient and stylish way to manage your time at home, in the office, or at school. Choose the YS, F4, or F6 model according to your needs and enjoy more efficient time management every day.

(i’m reviewing the hexagonal “f6” model and also comparing to the “f4” cube model)
Pros:
– 6 vs 4 sides (has 1 minute option and “stopwatch” function although it can also be used as a 99m59s timer)
– option of absolutely complete silence when switching timers and when alarm rings (f4 model cannot be completely silent and the most silent option is vibrate)
Cons:
– must cycle through all 3 sound options when switching sound options (beep -> vibrate -> silent)
– no option to set a custom timer, for example, 36min, unlike the f4
– can only function as a gravity timer, while the f4 has a manual timer mode where you can ignore the gravity function
Also, i’ve found that the f4 consistently lasts for 14 days of usage before needing to charge again, but i haven’t had enough time to test the f6, though i’d assume it’s similar. Overall, if you’ve never had a “gravity timer”, i think any of these will be a gamechanger possibly. Very useful and smart design

12 days delivery to the US. Really nifty tool that lets you set automatic timers by placing the cube in certain ways. There are 4 preset times (5, 10, 30, 60 minutes), but there is also a mode where you can set a custom timer. Charges via USB-C. Highly recommended, especially if you can find a lower price by comparing sellers. I think it would make a nice office-themed holiday gift, or even just for yourself if you have time blindness or trouble keeping track of time/staying on tasks. Easy to use for the Pomodoro technique as well.

Great tool for productivity check – would be cool if the screen side was even so you can’t scratch it when flipping
