This is an app that allows you to record study time and check the history with pie charts and stacked bar graphs. - Counting study time The app counts. Select a subject, set the study time, and count to record study time. If you close the app or perform other operations while studying, the count will be interrupted. - Register subjects By registering subjects, you can record which subjects you studied. By recording each subject, you can understand which subjects you do not have enough study time. - Study history Displays daily study time in a stacked bar graph. Recheck your study time by looking at your past history. If you do not have enough study time, make sure to set aside time for studying. - Advertisement This app is free to use, but ads are displayed. To avoid interrupting your studies, ads are displayed only after the countdown is completed so as not to break your concentration. - Purpose of this app This app was created for children who tend to study only in the subjects they are good at. The study time for subjects you are weak at tends to be short. By visualizing the time you study, you can understand the lack of study time for subjects you are weak at. I hope this will lead to improved grades for everyone.
