Greg Pierce, the developer of Drafts, launched a new contact management App today, Interact. Interact is a powerful contact manager for iOS. It allows you to quickly manage and group contacts on iOS. You can also use Interact to quickly sent group messages or emails and, perhaps my favorite feature, create or update contacts by selecting text and saving it to the scratchpad where interact will use natural language parsing to identify the names, emails, phone numbers and other details and automatically sort them into the proper contact fields.
Interact is $4.99 on the App Store for a limited time. You can learn more on the Agile Tortoise web site.
