## What is OneDay Matter?

OneDay Matter is a clean, ad-free countdown and anniversary app.

It is designed for the days you do not want to forget: birthdays, anniversaries, exams, trips, plans, traditional festivals, lunar birthdays, or any date that matters to you.

Add a day quickly, then open the app to see whether it is coming up, happening today, or already in the past. The Home screen uses natural-day counting and supports pinned important days, plus repeat rules for never, yearly, monthly, or weekly events.

OneDay Matter supports both Gregorian and lunar dates. You can record common lunar dates and traditional festivals, making lunar birthdays, Spring Festival, Dragon Boat Festival, Mid-Autumn Festival, and other important days easier to see.

Put important days on your Home Screen. The current version supports small, medium, and large Home Screen widgets. Widgets show the most relevant day based on pinned priority or nearest date, helping you keep important dates visible without opening the app.

For dates you want to remember ahead of time, you can also set a local reminder for an individual event. Reminder delivery can be affected by iOS notification settings, Focus modes, Notification Summary, and system behavior. OneDay Matter does not use cloud push and does not guarantee notification delivery.

Main features:

- Record important dates and anniversaries
- Show “X days left”, “Today”, or “X days passed”
- Support Gregorian and lunar dates
- Support never, yearly, monthly, and weekly repeat rules
- Pin important days
- Manually order multiple pinned days
- Edit and delete records
- Use small, medium, and large Home Screen widgets
- Set local reminders for individual events
- Choose Follow System, Simplified Chinese, or English language
- No ads, membership, subscriptions, in-app purchases, or paid tiers
- Records are stored on this device

OneDay Matter does not try to be complicated, and it does not get in your way.

It does one thing: help you remember important days and see them when they matter.

About local storage:

Records in the current version are stored on this device. You do not need to register or use an account, and records are not uploaded to the developer’s server. Please note that deleting the app may also delete your records. Account sync, iCloud sync, cloud backup, export/import, device migration recovery, data recovery, and multi-device sync are not supported in the current version.

### 4/5 — 建议

*2026-08-16*

很喜欢这个app，足够简约，体积足够小，是我想要的，但有个小小的建议，建议重复这里可以增加一个天为单位，另外，这个单位应该是可以赋值的，也就是，类似2周，3个月，4天这样
