The Friend Reminder app lets you create date-time and location triggered notifications related to your contacts and friends. You dont have to maintain an additional friend-list but simply choose from your existing contacts in your native contacts app.
The idea behind Friend Reminder is that your friends are the anchor point, around which you plan to be notified and reminded.
Schedule "Time Events" as reminders without cluttering your other calendars.
You can also use "Location Events"!
For example think about getting notified by your phone in order to get in touch with a long forgotten friend when you get close to a certain location where she lives. Or get reminded to make a call to a special someone when you arrive at your destination, ...
Friend Reminder provides a nice way to keep your calendar clean and avoids syncing "every" information to other devices.
We hope that this little tool helps you to simplify your lives :-)
