Seesmic is having a huge week. The startup that develops Twitter and Facebook clients for the web and desktop just unveiled a native Windows client at Microsoft’s Professional Developer Conference earlier this week. At the Real-Time CrunchUp today, Seesmic is launching its first venture into the mobile space with impressive apps for both the Android and BlackBerry, which are now available for download here. This is a pivotal moment for Seesmic because the startup is now conquering all the mediums—web, desktop and mobile. I sat down with Seesmic’s co-founder, Loic Le Meur, to test out the apps.
The BlackBerry App
The BlackBerry app, which works with the devices running OS 4.6 or higher, has a extremely sleek nice interface, which is optimized for BlackBerry users with all sorts of efficiencies. You can quickly change from different timelines, easily switching from your inbox, to mentions, to direct messages. Plus, you can monitor various Twitter accounts within one appp. When you send a Tweet, you can shorten a link via Bit.ly, and upload pictures or videos via yFrog. One compelling feature is the ability to email a Tweet to a contact directly from the Tweet.
The app also includes search (Seesmic stores all the info in cache) and will also feature notifications of new Tweets and DMs while you are scrolling through email (a little raccoon will pop up with a number of new Tweets, says Le Meur). And hands down the two best features of the Blackberry app is the ability to see your Twitter lists directly from the app and geolocation, so you’ll be able to tweet your location directly from the app. Seesmic just added geolocation, as the API was released yesterday. Facebook integration will be added in the near future.
The Android App
The Android App also features a very sleek design and a user-friendly UI. The most noticeable advantage is how fast the app is. Le Meir says the app is native to the Android and claims its the “Tweetie for the Android.” Via a touch interface, you can easily navigate though threaded timelines, direct messages, different accounts, and @replies. And you can email Tweets as well as easily switch to landscape mode.
When you Tweet you’ll see options for Tweeting publicly or via a DM and shorten links through Bitl.ly. You can easily attach a picture or video via yFrog. And here’s the kicker-you can also upload videos directly to YouTube via the app. You can also access other users profiles, see his/her Tweets, who he/she is following and then follow the users. In addition you can also block or unfollow a user.
While Twitter rolled out the geolocation API yesterday, Seesmic hasn’t integrated its API into the app. But the app still features a geolocation tool that lets you embed your location in a Tweet via the Android’s GPS, which will show your location on Google Maps.
The app works with all models of the Android and was optimized for the newly launched Verizon Droid. While the Android app doesn’t have list functionality or Facebook integration, Le Meur says these features will be added in the near future. 
The iPhone App
A few months ago, Le Meur informed me of Seesmic’s iPhone app. But the app is still being tweaked. While we don’t know the in-depth details of the iPhone app, we do know that it will have functionality for both Twitter and Facebook status updates.
Seesmic’s BlackBerry app will face competition from UberTwitter, OpenBeak (formerly TwitterBerry), Tweetcaster and perhaps even a RIM-developed Twitter client. But Seesmic’s app is chock full of nifty features, such as lists and perhaps even Facebook integration in the future. It will certainly be a viable contender in the space. The Android app will face competition from a smaller group of Twitter clients for the Android, which include Twitdroid, Swift, and TwitterRide. But like the BlackBerry app, Seesmic’s Android app is fast, sleek, easy to use and will also have Facebook built in soon, making it very attractive.
As I wrote above, Seesmic is now full throttle in developing numerous offerings for the web, mobile and desktop. Le Meur says the Windows clients had 10,000 downloads within 12 hours. I fully expect the the Android and BlackBerry apps to receive the same response. As the startup continues to develop new and innovative products, it is slowly encroaching on rival Tweetdeck’s market share and attracting a whole new set of followers as well. But a little friendly competition is never a bad thing between technology companies.
