Birthdays Manager Reminder is a free Android application developed by Passionate Developer under the Social & Communication category. It is a lightweight app that doesn't require its own database or data storage. Instead, it works with contacts in your Android device and uses the device calendar to display lists of all birthdays in your contacts. It also shows lists of all contacts without birthdays so you can manage them easily. The app features a smart widget-shortcut that displays information for the next five days.

The resizable widget (1x1) is extremely small and shows a list of upcoming birthdays to inform you whose birthday is next. If you wish to see more data, you can enlarge the widget size. The app also has a status bar notification that reminds you to greet your friends on their birthdays. Just tap the notification to open the contact's card where you can call or send an SMS or email message. The application supports multiple accounts and all types of events, including birthdays, anniversaries, and more. All widgets are configurable, and you can define color and transparency for any element. Birthdays Manager Reminder is a Google advertisement-supported application that needs full access to the internet, but it works without internet connection too. If you want to help translate the application to your language, you can email the developer.
