This app will allow you to input all the events which you have throughout the year (every year) such as birthdays, anniversaries and much more. Then you will get the option wether you would like reminders for each event the day before and seven days before. This is so that if it is an event such as a birthday and you need to buy a gift then being reminded seven days before gives you some time to acquire that present.
From when you input each event into the app, it will then remind you every year, so you will never forget again!
