Dock is an iPhone app that acts as as screensaver of information when your iPhone is not in use. While your iPhone is docked at your desk, Dock will scroll through weather, RSS, Twitter, Facebook, Clock and Stock widgets.
Dock is a very simple and easy to use app. You can either have Dock scroll through the information in one widget (like tweets from Twitter), or you can have Dock randomly scroll through information from all the widgets you've selected. If you are interested in something that scrolls by, tapping it will give you more options. For example, you can enlarge photos, reply to tweets, "like" Facebook photos and comment on them, and more.
In Settings, you can choose to have the information scroll by every 2, 4, 6, 8, or 10 seconds and mark which widgets you want active. You can also adjust the refresh rate of each widget, but unfortunately, the fastest refresh rate for Facebook and Twitter is 5 minutes. I'd like to see that reduced down to at least a minute.
My other little complaint is that Dock doesn't include a light colored theme. I have never been a fan of light-on-dark color schemes because it hurts my eyes and makes me squint (I have very sensitive eyes).
Dock turns your iPhone into a fantastic little utility while it's docked. It runs great and displays information nice and big so that it's easy to read.
