Star Ring Punch provides users with an easy-to-use punch card service. The events that need to be punched are set intuitively through the calendar, and you can see the events that should be completed daily on the calendar. By persevering daily punching, you can develop a habit without knowing it. Punch events can be divided into daily or weekly cycles. You can set the start date and end date of the punch event. The system calculates the number of days that need to be punched and marks it on the calendar. The calendar shows the punch event that needs to be completed in the current date. The user can decide whether the event has been completed according to the set time. The app also provides a query for all events, making it easy to see all events, as well as the date the event lasts and whether the date is complete. It is both intuitive and convenient.
