You associate contacts with their Fryncuencies, i.e., how often you want to speak to them. Frync monitors your call history, and notifies you when you haven't spoken to a contact at his or her fryncuency.
Frync does not overload you with notifications to call all your friends at once. Instead, it randomly selects upto 2 friends you have not spoken to at their fryncuency, and reminds you to call them. You can also choose to be notified only on weekends.
If your New Year resolution is to keep in touch with your friends and family, then Frync is the app for you!
This app is similar to the app "Call your folks".
