AgeMemo is a free Android app developed by hayandroid that helps you keep track of important dates, such as birthdays and anniversaries, and manage your schedule. It has a simple and user-friendly interface that allows you to create groups like "Family" and "Friends" and record their names and birthdays. You can easily see the age of the members in each group and even check their age at a specific date in the past or future.

AgeMemo also lets you record anniversary dates and events and set reminders so you never forget them. You can customize the reminders and even display the remaining days until an event. If you have a busy schedule, you can use AgeMemo for schedule management. By displaying a list, you can see how many days are left until your next appointment or event.

The app also offers a feature to specify the date of death, and if you set the anniversary of your death, it will automatically switch to the year of enjoyment display. Additionally, you can open a specified group when the app is launched, which can be set on the setting screen.

Although the app displays ads, it is a completely free app. With AgeMemo, you will never forget important dates again.
