Shiyu- Day Countdown

Shiyu is a quiet countdown and anniversary app for birthdays, milestones, exams, trips, payments, and the dates that matter only to you. Open the app to see today and what is coming next. Each day can include a date, repeat rule, reminder, icon, and note. Switch between days, months, and weeks in the detail view, or use the calendar to see what falls on a particular date. Optional end dates, inclusive start-day counting, and exact times are available for more detailed timelines. Groups and archiving keep the list in order. Search, the calendar, and Home Screen or Lock Screen widgets each offer a different way to find the date you need without opening the app every time. On iPhone Duo, the list and detail view can sit side by side. Days are stored on your device by default. If iCloud is available, they sync through the private database of your own iCloud account. JSON import and export make it possible to move your data or keep a copy. Shiyu has no account sign-up, no ads, and no third-party analytics or advertising SDKs. You can create and import as many days as you like for free. Reminders, iCloud sync, export, and all current Home Screen and Lock Screen widgets are also included. A one-time lifetime purchase unlocks other event colors, full group management, all card backgrounds, and advanced date options. Existing data is never deleted when membership changes.
