Helium is a dead simple task management tool to implement Getting Things Done (GTD) and Inbox Zero. Helium connects to your email (IMAP and Exchange) and Evernote to transform information you’re already processing into actions. Delegate tasks to anyone whether they use Helium or not. Helium works on Windows, Mac, and iPhone (Android and iPad on the way) without being stuck inside of an Internet browser.
Helium enables users to maintain a single workflow across systems. For example, you can label an email as “someday” in Gmail and it will automatically appear in Helium in my Someday list. Once I complete the task in Helium it will move my email to Archive in Gmail. This approach makes it really easy to practice GTD and Inbox Zero in one simple approach.
