Features:

• all Twitter operations supported
• set favorites
• tag specific users to follow separately
• translation of foreign language messages

The Good:

Nambu Touch for the iPhone® follows on the Nambu Network Inc.’s Nambu for Mac OSX 10.5+. It has a good-looking UI and supports just about every Twitter operation you could want, down to searching and tagging specific users for filtering/following. Submission via Ping.fm is a nice feature.

The Not-so-Good:

Nambu Touch is a very promising application that already supports many useful features. It is compatible with the iPhone® and iPod Touch™ with the iPhone 2.1 software update. Also, be aware that it costs $1.99 at the App Store.

Features:

• browse and @reply followers
• send photos to TwitPic

The Good:

The Not-so-Good:

Sometimes the focus can seem to be too much on nifty features like “shake and erase”, but overall, Twitfire gives few reasons to complain.

The Good:

La Twit is a very good aplication for the iPhone, packed with useful features. Ease of use is primary with La Twit. It even has a transparent post box so you can view prior posts while composing one.

The Not-so-Good:

Of course, we always want every app to do everything for us, and complain bitterly when it fails. La Twit has bitten off a lot, and some of the features (although all useful) take a while to get used to on the iPhone. Support contact is only via “form” (as opposed to phone or email), and we aren’t sure about the turn-around time.

NatsuLion is a simple (or simplistic) Twitter app for Mac OS X.

Features:

• Display timeline
• Post a message
• Create a favorite
• Replies including messages contain @ are emphasized
• Input support for “@<ID>”
• Growl Notifications (replies are notified with a higher priority and stickied by default)
• Manage unread tweets

The Good:

NatsuLion is a basic desktop app for using Twitter, and it accomplishes its limited goals quite well. Graphics are good and the Growl notifications are a nice feature. For those who are interested, NatsuLion’s website offers a link to its source code. Of note, there is a version of NatsuLion for the iPhone®, available at the App Store for free (our comments for the desktop version apply to the iPhone® version too).

The Not-so-Good:

As we mentioned, NatsuLion does its job well, but its job is rather limited in scope. Also, the supporting info on the website appears to be in Japanglish (can’t really blame them, these guys are from Japan after all), and that can be either very amusing or very frustrating, depending on the time of day.

Summizer is an application for the iPhone® that accomplishes what Twitter Search does in a browser environment.

Features:

• perform power searches for tweets
• view trending topics in Twitter

The Good:

Summizer uses the Twitter Search API to dig through the database for related tweets. If you’ve got a topic that you search for more often, you can save that search for later use for the sake of sparing your thumbs. Summizer also automatically pulls down the latest trending topics from Twitter, giving you a quick and easy way to see what’s on the collective mind at any given moment.

The Not-so-Good:

Summizer is currently focused solely on searching and trend watching, so it doesn’t offer any means of logging in, tweeting, or following users. Also, Summizer comes at a price: $4.99 from Apple’s App Store. Some say it accomplishes the same thing that Twitter Search does (running just fine thank you if you bookmark it on your iPhone®).
