Ever feel like your iPhone needs a little more Dieter Rams in its life? Give it some with the T3 Music Player ($1). Inspired by Rams' iconic Braun radio of the same name, it sports a clean white interface with a circle in the middle for controlling playback (sounds familiar)? Not content to simply ape the T3, the music browsing interface takes after Rams' 606 shelving, and lets you sort your playlists alphabetically or by rank.
Just because an app sports a clean interface doesn't mean it can't offer a lot of depth. Haze ($1) is a deceptively simple, gesture-driven weather app that uses colors and animation to give you an at-a-glance look at the weather. While it's easy to see the current temperature and warming/cooling trends, a few swipes can reveal a wealth of information, including a five-day forecast, sunrise and sunset times, cloud coverage, high and low temperatures for the day, windchill, wind speed, wind direction, precipitation chances and amounts, humidity levels, and even atmospheric pressure. All from an app that only displays a single number at startup — not too shabby. [Scouted by Freddy]
If you've ever heard of Merlin Mann's Inbox Zero concept, then you know you can boost productivity by focusing only on the emails that matter. Mailbox ($Free) is designed to do exactly that. It features a simple, gesture-powered interface that quickly lets you archive or delete mail, or "snooze" it until later so you focus on more important messages — they'll return to your inbox later. In addition, it organizes conversations into a chat-like structure, making it more easy to follow long threads. It's available now for the iPhone and works with all Gmail accounts, but you'd best be prepared to wait a while before you get to use it — last time we heard there was quite a line.
