トレカレ

Torekare is a calendar app that makes schedule management more efficient and easier to understand. No login or membership registration is required. Simply enter only the necessary information, such as titles and notes, to organize your daily schedule. Personal schedules are stored locally on your device and are not synced to the cloud, so you can start using it without any extra setup.
Another feature is that it displays shared schedules such as events and campaign announcements registered by organizers, as well as tournament information. For each schedule, you can check information that helps you decide whether to participate, such as the number of participants and the location of the event, so you can easily incorporate events that interest you into your schedule.
You can view your daily schedule and important information all in one calendar. It also supports notifications, so you can manage your schedule at your own pace while preventing forgetting things.
