App Description
Manage D-days with ease
Hello,
I'm happy to introduce a lightweight and easy-to-use D-Day app.
* Countdowns
Set the time for your D-Day and easily check the remaining or elapsed time.
The time is calculated and displayed in multiple formats (months, weeks, days, hours, etc.).
* Anniversaries
Set anniversaries and check dates related to your D-Day.
You can also use it like a date calculator.
* Memos
You can create memos related to your D-Days.
The date and time are recorded with your memos.
It is recommended when you want to keep tracking on your schedules, or keep the records of them.
* Notifications
Schedule notifications for your D-Days.
You can schedule multiple reminders and write whatever message you'd like. You'll receive push notifications at your set times.
Thank you.
