I was talking to a colleague today about how I quickly capture notes on my iPhone and iPad. My goto app on the iPhone is Drafts (by Agile Tortoise). Drafts lets you get stuff out of your head and on to your device quickly. Once you've captured the information, you can decide what to do with it (e.g. send to Facebook, Twitter, save as a text file, Omnifocus, or a whole host of other possibilities).
While Drafts was great on my iPhone, it wasn't available on the iPad--until now ($2.99 on the App Store).
Drafts is now on the first screen of both of my iOS devices. Thanks Agile Tortoise!
