Recontact helps you make the most of your Google Contacts, so it's easy to remember who you've met and strengthen your relationships.
Each day (or how often you choose), Recontact sends you an email with a few of your contacts for you to review.
You can use the webapp to add notes, tags and meaningful dates. Plus, it's easy to favorite your important ones, and quickly delete contacts you no longer want to keep.
And if you use Gmail on the web, you can do the review right in the email.
