There are two things hot these days, Twitter and iPhone, so if you need to use them together, there are few iPhone apps through which you can tweet very easily and effectively. Let’s check them.
Tweetie (atebits)
Tweetie is a rare app that moved from iPhone to Mac, and it’s easy to see why: this rock-solid and user-friendly mobile Twitter client has a great interface and deftly handles multiple accounts.
It’s not as customisable and feature-packed as some, but the care, polish and performance evident in the app more than make up for that.
Twitterrific (The Iconfactory)
Twitterrific is the client jostling most with Tweetie for the position of iPhone Twitter king. The app is terrific if you’re after a seriously feature-packed and customisable client, and it’s also beautifully designed, as you’d expect from The Iconfactory.
Its complexity means Twitterrific isn’t as immediate as Tweetie, but it’s just as good—and the ad-supported version is free.
Birdhouse (Sandwich Dynamics)
Words like ‘crazy’ and ‘too much gin’ were banded about when Birdhouse was first announced – after all, why would anyone want a drafts app for 140-character tweets? But a few minutes should make a convert of any serious Twitter aficionado, due to Birdhouse’s ability to draft in Airplane mode, rate and sort drafts, publish and ‘unpublish’ tweets, and back-up everything to email.
Other Twitter clients are busy ripping off Birdhouse’s functionality, but you’ll have to pry this wonderful app out of our cold, dead hands.
Twitfire (Eric Allam)
You might think a post-only Twitter client a pointless waste of time, but Twitfire can instead save you time, because it enables you to post without getting distracted by replies, direct messages and Stephen Fry.
Twitfire’s also surprisingly feature-packed, enabling you to attach images to tweets, browse the web to find links (which are subsequently auto-shortened via is.gd) and reply to your adoring followers.
Twuner (Krystronix)
This mildly crazy app turns your Twitter feed into a radio station of sorts, enabling you to take in tweets in passive fashion.
You can optionally play iPod music in the background, which fades out when tweets arrive; said tweets are then read aloud in posh-robot fashion, before your music returns. Various voices and speech rates, inline transcripts, and support for multiple accounts ensure Twuner can be tuned to suit.
Ego (Garrett Murray)
Although not strictly a Twitter app, Garrett Murray’s Ego stats tracker includes support for the service. If you don’t want to mix with your peons, but are nonetheless intrigued by their current number, Ego provides the best-looking means around of tracking such values; and if you’re also a Google Analytics, Mint, Feedburner or Squarespace user, Ego’s a must-buy.
Boxcar (Jonathan George)
If you’re forever missing (or avoiding) Twitter direct messages and mentions, Boxcar places such things front and centre by using OS 3.0’s push notifications.
Usefully, this app is big on simplicity and low on ego, since once you have your message, it hands you over to your favourite Twitter client.
Boxcar’s perhaps on borrowed time, until your favourite client bundles similar push notification, but for now it’s a one-trick pony with a particularly shiny coat and good teeth.
Birdfeed (System of Touch)
Although not a particularly distinctive Twitter client in many ways, Birdfeed is nice enough, offering a clean, simple means of accessing multiple accounts. However, it offers two features that make it worth consideration: timestamp indicators help you find where you last stopped reading a stream, and local caching enables you to catch up on past tweets when on an airplane, in a submarine, or in the bit of your correspondent’s garden where the network inexplicably cuts out.
