Free Time Picker

■ How to use
When you open the app, you will be asked for permission to access the calendar.
Select the date you want to search for free time from today, tomorrow, this week, next week, this month, next month, or custom.
For the minimum free time, enter the required free time. If there is more free time than the time entered here, it will be selected.
Transit time is the time it takes to transit to the actual event location. The free time considering the minimum free time and transit time is selected.
If you want to ignore the all day schedule, check Ignore all day.
If you want to ignore the holiday schedule, check Ignore Holiday.
Finally, tap the search button to display the available time in a list.
Please copy the free time from the share button on the upper right and paste it on e-mail or SNS.
