Human will is sadly weak.
So you cant keep doing things depending on the will.
Even if people think "Im different now. This time is so serious.", unfortunately nothing changes because they still depend on their will.
This means a habit app needs to bring out the power of consistency without depending on human will.
And this app does it.
People can keep doing things by making small action based on correct knowledge.
So this apps design is based on correct knowledge.
Wrong idea 1. Try many things at once.
Solution 1. You can set only one thing at a time.
Wrong idea 2. Try endless challenge.
Solution 2. You set the goal first. And every time you open app you see how many days left.
Wrong ideas and solutions 3, 4, 5, ...
a lot.
Also, as a result, this app became so simple and takes only about 3 seconds a day.
If you like simple app or you have something to continue, try it!
