Siri investor Shawn Carolan has launched a new email and task management app, Handle, at the TechCrunch Disrupt conference. The web-based service with iOS companion app is based on the same CRUD (Create, Read, Update, Delete) approach as the highly popular Mailbox iOS app …

Carolan says he created the app with co-founder Jonathan McCoy when he couldn’t find an existing solution that did everything he wanted.

From a brief review of the video, Handle appears to be somewhat more sophisticated than Mailbox, fully integrating emails, other tasks and calendar appointments, but we’ll be carrying out a head-to-head review of the two later to find out how they compare.
