The only app I miss from Android is BirthDayDroid. This app takes birthdays information from contacts and send notifications about them. Also provides convenient interface too look at the upcoming birthdays. GNU/Linux phones also have contacts and also support birthday fields. But is there a similar app to notify about birthdays?
You could add those birthdays as events in your calendar instead of adding them in contacts.
It’s a good option. I just hoped that I can somehow import this info from my current contacts.
