At a glance

Dex is sharply focused on "don't lose touch" - it adds reminders + activity tracking on top of LinkedIn-style integrations. Contact Book does that too, and adds gifts, life events, pets, family relationships, and a journal. If keep-in-touch reminders are 80% of what you want, Dex is excellent. If you also remember birthdays, family details, gift histories, and want all of it in one place, you're more at home with us.
