About this app

Even though I'm an examinee before the test, I'm not motivated.
The deadline is near, but I can't concentrate even before the qualification exam.

Many people have such human-like worries.

But it's okay.
There is a reliable technology devised for such people.
(Called the "Pomodoro Technique")

1. Set a time limit with a timer
2. Rest when finished
3. Repeat it
The procedure is so simple that you will want to say, "Is that effective?"

However, as you can see, this is surprisingly effective.
It is a centralized app created based on such technology and the voices of people who actually used the app.


■ Functions of this app
1. Set a frequently used timer
For work: 10 minutes, 25 minutes, 60 minutes
For breaks: 1 minute, 5 minutes, 30 minutes
And so on.

2. Freely classify work and record / manage time
Please classify for ease of use.
・ In the subject (English / Mathematics / Arithmetic / Society / History / Science / Physics / Ancient writing, etc.)
・ By work content (email / meeting / planning / work plan, etc.)
・ Study method (listening / word memorization / grammar / workbook, etc.)
・ Other freedom (programming / illustration (picture) practice / novel writing / medical office examination / secretary test / zazen, etc.)

3. Look back on the graph by concentration and day of the week
"For now, don't go according to plan. Okay."
"I can't concentrate on teleworking days. I have to be more aware of it."
"I'm not motivated and inefficient in my assignments and homework. Let's limit the time and finish it quickly."
It seems to be useful when reviewing work schedules and study methods.

4. Learn the tips of concentration in the column
・ Know and prevent smartphone addiction measures
・ Stop behavior that impairs concentration
・ Work → Break → Importance of work interval
And so on. (Contents are subject to change in updates)

Just set a time limit with a timer and work hard at work and learning.
It's just that simple app, but it may be of some help.
