iOS: You have lots of options for productivity apps on the iPhone, but one of the big problems with having so many options is that they don't integrate with each other that well. Dispatch is an email app that aims to solve this problem.
At its core, Dispatch is a competent email client with a nice set of gestures to work through your email. It also has a built-in snippet system similar to TextExpander, as well as a handy auto-salutation system that saves you a surprising amount of time on your email.
Dispatch operates more like a central hub for your workflow. You can use Dispatch to send notes about an email to other apps, such as Evernote or OmniFocus. You can create reminders to follow up on an email in an app like Due or Things. Even addresses or dates can be sent over to other apps. Likewise, links can be saved to Pocket or Instapaper without ever leaving Dispatch. Essentially, the purpose of Dispatch is to keep you within the app as much as possible so you can get things done quickly.
In a way, Dispatch is similar to one of our favourite note-taking apps, Drafts, because it works like a control centre for handling your email. It doesn't support every app out there for exporting tasks, but it does include the big ones. If you're looking for something that integrates with your favourite apps, Dispatch is a fantastic option.
