Contacts+

Contact information management
Contacts+ is a contact management tool that integrates across multiple platforms. It allows you to sync across multiple devices and accounts to create an all-inclusive address book for your network. You can use Contacts+ to create custom dossiers that attach to your Google Calendar events. This allows you to receive information about the other attendees of these events based on who has RSVP’d. This will prompt you to add those people from the event to your Contacts+ address book, which you can opt out of. This FullContact Dossier tool currently only works with Google Calendars, but it will allow you to get to know people at events and seamlessly add participants to your address book. The pricing plans for Contacts+ are as follows: Basic: $0 per month Premium: $9.99 per month Team and Small Business: $14.99 per user per month.
