Ninety - 90 minutes ToDo

"90 minutes" is the limit that human beings can keep their concentration, which is neuropsychologically called the Ultradian Rhythm.
So, why don't you divide your day into every 90 minutes to maximise your productivity?
Ninety is a task management application to boost your brain power.
This very simple single page App is for those who want to manage ToDo in every period of 90 minutes.
You just need to type your tasks into the period card.
Ninety notifies you the tasks for the next 90 minutes when the period begins.
Today, ToDo Apps are becoming more and more multifunctional, in other words, becoming complicating.
Ninety might be too simple. However, that is what we need.
Please enjoy your life with Ultradian Rhythm, and Ninety.
