What’s the easiest way to capture tasks and quick notes on the go? Some might say OmniFocus for iPhone is the way, some are in bed with Simplenote. I say the easiest and fastest way to capture tasks in seconds has always been this: email them to yourself.

I know, it’s archaic. But it works. And if you’re running your email account on Gmail, you have an amazing amount of tools to play with to setup great filters to sort the inbox for you. Not to mention the latest feature Google added to Gmail, the Priority Inbox: if you’re used to emailing tasks to yourself and you tell Google those emails are important, you’ll never miss one.

That’s why I’m in love with Captio.

Captio for iPhone is a $0.99 app that does one thing: it lets you email text and pictures to yourself. You enter a personal email address, you write something and hit Send. Done. In seconds you’ll receive an email from Captio’s system (and thus the possibility to easily create a filter) with the text you jotted down.

There’s not really much to add. The icon is nice, the app is optimized for iOS 4 and the Retina Display. $0.99. You know what to do.
