This is an application that makes it easy to record the degree of achievement of the goal that you want to make it a daily habit. Because it is simple, it can be used for various purposes in general purpose. (Exercise, study, hobby, housework, health, childcare, anything.) Since usage is easy enough to handle with children, it probably will not get lost.   * You can register multiple goals (themes). * You can change the color for each theme. * You can also write a memo in addition to the actual results of each day.   * Two ways of registering results every day 1, stamp formula (I did it / did not do it) · Put away one place every day · Write a blog · Take a walk of a dog · Stretch -> Show monthly achievement days and achievement rate   2, Register as a number · Jogging (km) · Abdominal muscles(times) · Study (hours) · Reading books (volumes) -> Display monthly total value or average value   Generally it takes both will and effort to start new things. Even if you start with full motivation at first, keeping that heat for a long time is hard. However, please feel that feeling that "I want to start something, let's continue, change my self".   To continue things, you need a little trick. "5 tips for continuing goal" is introduced in the application. Even if you do not do anything and you give up if you do not continue, if you acquire the "continuity tips", something may change.   Small small stacks of everyday become a great force one day and may change your life.   This application and its developers (I) softly cheer you for your new challenge in the distance.
