Each month, the best new iPhone apps — and some older ones — are considered for admission into Gizmodo’s Essential iPhone Apps Directory. Who will join? Who will live? Who will die?
The Month’s Best
Layar, the first camera-based AR app to really blow us (or anyone) away, has quietly slipped into the App Store. As with the Android version, the app overlays all kinds of information onto a live view of the world around you.
And the less obvious, but ultimately more important one: Layar layers, which let you install user-generated overlays of all different kinds of information, like this one, which tracks US government bailout spending. Free.
It’s the most polished Twitter app yet, oozing slickness with every swipe. Yet, it’s exploding with new features, and still really fast. It manages to cram in every possible feature you could possibly want in a Twitter app — offline reading! — without feeling too complicated or bloated.
It’s four dollars, even if you had the previous version, but totally worth it.[imgclear]
Rock Band: It's not perfect — controls can be awkward, and the singing mode isn't really a singing mode, but it represents the first major rhythm franchise to hit the iPhone, and it bear gifts: Great graphics, decent, familiar, song selection, and multiple instruments.
App Directory Inductees
• Layar, for being a free, solid platform for augmented reality on the iPhone, which will be made great by new layers.
• Tweetie 2, for being even better than it was before, and for being the best iPhone Twitter app out there, assuming you're willing to shell out a few bucks.
• Instapaper, for its tragic exclusion in the last update: the ability to save pages for offline reading is useful for just about anyone, but absolutely essential if you're a frequent flyer or subway rat. There's also a pro version.
And Farewell To...
• Tweetie, for you have been replaced; cannibalised by your own child.
What counts as an essential iPhone app changes all the time, and so should our guide: If we've missed anything huge, or you've got a much better suggestion for a particular type of app, let us know, or say so in the comments. We'll be updating this thing pretty frequently, and a million Gizmodo readers can do a better job at sorting through the app mess than a single Gizmodo editor. Enjoy!
