I’ve looked at pretty much old iOS podcasting apps. Pocket Casts remains one of the weirdest, but it’s also the best available, and it’s been updated regularly (some updates have even removed a bit of the craziness).
1Password is fantastic, and the best argument for why it should be possible for developers to write plugins for iOS’s Safari.
On many mobile platforms, changing the screen’s brightness or getting to your data usage information is pretty simple. On the iPhone, it’s not, which is why I have David Barnard’s Launch Center on my home screen. Among other things, it allows me to jump directly to different screens of the Settings app.
Besides the stock Apple ones, I use Instacast to listen to great podcasts from 5by5, 70 Decibels and The Verge. I use AppShopper for iOS (and .com) everyday to do the @MacStoriesDeals posts and am currently testing TouchArcade which works with AppShopper. You guys will love it. Agenda is my Calendar.app replacement and Sparrow (currently beta) is great. Tweetbot for my twitter habit, Instagram for sharing pictures (I recommends an olloclip by the way), and Reeder for RSS. Reminders was a nice addition to iOS 5 especially if you have a 4S with Siri.
Thanks for checking out my home screen!
