TKBirthdayReminder is a beautiful birthday list. Once a day you receive a notification that reminds you about upcoming birthdays. You can place a widget on your home screen, too.

The birthday dates are stored in your Google Contacts. So there is no need to backup an app-specific birthday list. On a new device just reinstall the app and - voila.

The app is free of charge, contains no ads, does not track you, and does not collect your data. It looks great on foldables and tablets. And it is open source, which means that everyone can have a look at its source code.
