Track business relations calls

Found a great app to track how often I am calling my business relations, and if I didn't call then for a month, an alert will go off. I need keep in touch with them and this is THE prefect app to do so.
Here are the main features:
★ identify important clients and friends you want to call regularly.
★ alerts you when you haven't called a contact for a specified time.
★ splits contacts into business and personal categories.
★ creates an overall call schedule for personal and business contacts.
★ creates custom call schedules, for more or less regular contact.
★ Setup only takes a few seconds.
