This is the best smartphone app to reduce reliance on smartphones for today!
Set your "Focus Time" and concentrate for a short time!
It prohibits smartphones and encourages concentration.
*On July 28, 2019, in an article on smartphone addiction in the Yomiuri Shimbun thats the most famous newspaper in Japan, it was introduced as a recommended app to shake you free from addiction!

*I cant stop playing app games...
*I keep looking at SNS...
*If a message comes, I stop studying...
*I feel kind of worried if I don’t touch my smartphone...
Don’t you have a worry, youre addicted to smartphones.

I know, but I cant stop.
I want to do my best.
We support you if you think "I want to do my best".

There is a limit to human concentration.
Set a short time as your Ganbari Time (Time to work hard), you prohibit your smartphone and concentrate on studying and working during the time!

I recommend it to anyone who wants to improve themselves,
highly conscious people, people who have a sense of crisis but feel lazy, or people who have a feeling of trying hard!

*How to use it:
*After starting the application, decide the time to concentrate and start! The timer starts.
*The smartphone screen stays on during the designated time. You cant switch to the home screen or use other applications.
*An encouraging "great mans words" is posted on the timer screen. When you feel discourage, lets stop by looking at the words of wisdom.
*Your concentration is measured.
*You will receive a medal by accumulating measured results! Lets aim for a higher rank.
*Still, if youre concerned about message or email notifications, I recommend using [More Ganbari Time(Time to work hard)], which can only be started when Internet access is disabled!
Aim for 100% concentration and make it a habit to shake free from relying on smartphones!
