Study Timer - Pomodoro Timer

If you want to improve your study and work efficiency, we recommend this powerful study timer with time tracking.
A dedicated Pomodoro timer that helps you stay focused, combined with relaxing natural sound BGM such as waves and rain, supports your deep focus sessions.

This app lets you practice this widely used time management method with just one tap.

It also works as a study BGM app, time tracking app, and countdown app for important deadlines.


◆◇ What is the Pomodoro Technique?
A time management method developed in the 1980s by Francesco Cirillo.

It’s simple:

One set consists of 25 minutes of focus and 5 minutes of break, repeated up to 4 times.
After that, take a longer break of 20–45 minutes.

It’s a simple yet effective way to improve focus and productivity.

◆◇ How to use the app
Decide your focus time, break time, and number of sets,
then start the timer.

Since it runs automatically in cycles, no extra work is required.
* No need to press a button every time you take a break or refocus.
* If you use the same settings every time, you can manage time with one tap!
* Get notified by alarm when focus and break sessions end.

◆◇ Find a focus time that suits you!
A typical set is 25 minutes of focus and 5 minutes of break, with a maximum of 4 sets. However, if you feel that 25 minutes is too long for your focus time, try adjusting your focus time to 15 minutes and your break time to 3 minutes.

If you can't do 4 sets due to time constraints, you can change the number of sets. Please adjust according to your physical condition and time.

◆◇ Why natural sound BGM helps
Natural sounds like waves and rain are often associated with relaxation and better focus.
Listening to calming background sounds can help create an environment that makes it easier to concentrate.
Some natural sounds contain subtle rhythmic patterns often referred to as “1/f fluctuation.”
These gentle variations are commonly associated with a sense of comfort and relaxation.

◆◇ Change the background music according to your taste and mood!
