Mailbox is a free mail app for iPhone. It downloads your messages to a secondary cloud server before the messages hit your phone. I have no idea how they’re making money. This can’t possibly go wrong.[1]

I’m finding it a bit fiddly to make it work with OmniFocus, just because I’ve made it a point to turn OmniFocus into my only source when I go to look at what I have to do for the day, and now having to split to-do tasks between two places is—well, fiddly.  ↩
