You realize that the time has flown by. Has this ever happened to you? Even if you check the date and time, it is surprisingly difficult to correctly recognize the passage of time. We need a time display that is easier to understand and more memorable. This is how Hour Calendar was born. This app is a calendar-style clock. It emphasizes the disappearance of time and shows the current location in terms of time at a glance. It is the third clock of the app era, different from both analog and digital clocks. It is also available as a widget. Tip: Please use accessibility to increase the text size. You can change it only in this app. Expected Development: The following development is planned for Phase 1 * Layout settings (multiple time elements, time units below the hour) * Color settings We plan to offer this service on a subscription basis. The timing of provision will be determined based on usage. We plan to develop a timer function in Phase 2.
