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. Developer Contact: kim.beeefriends@gmail.com
