To-Do Today with calendar item

* If there is a problem with the operation of the app, such as updating the widget, please set App Settings -> Setting of Power saving exclusions.* To-Do Today is an application that allows you to easily and conveniently register and manage your to-dos. 1. It intuitively shows past to-do, today's to-do, and tomorrow's to-do. (past to-do can be displayed up to 7 days, and can be changed in the settings.) 2. You can sync events with Google Calendar. 3. You can easily check the remaining tasks through the completion mark. 4. You can check the same to-do every day by setting repeat. 5. You can always check the size of the widget on the home screen through the adjustable widget. 6. If you have something to do today, you can notify it with a notification bar. 7. You can change the app and widget design to any color you like. 8. You can check statistics on when and how much to-dos were registered. 9. The app is fast and lightweight by providing only the core features. User data entered in the app is only stored locally on the device or in a secure Google Drive during backup, and is never kept on external private servers. (No data leakage)
