Birthday Remind - GiftReminder is an Android application developed by Yukihiro Ogawa. This free utility tool app helps users keep track of birthdays, anniversaries, and longevity celebrations. It displays the current age and age on the next birthday, as well as how many years the anniversary is. Additionally, the app offers a list of people who have the most recent birthdays and anniversaries, and counts the number of days until the next event. Users can also set reminders for birthdays and anniversaries and record memos for each important person.

The app allows for the registration of both Japanese and Western calendars, and even if the year is unknown, registration is possible only with the month and day. Users can manage family members and relatives with labels and import information from the phone book. The app can be used even after changing models by linking with Google.
