Last November, Twitter was briefly named the number one photo sharing service with a majority of shares on the network coming from its official service. While this news was great for Twitter, it didn’t bode well for third-party services like TwitPic.

TwitPic is a web service that allows you to easily upload pictures to Twitter. Previously, this had to be done through its website, but now the company has released an iPhone app, complete with a photo editor and filters.

The app couldn’t be easier to use. Once you have logged in with your Twitter credentials, you can upload an image from your photo library or you can take a new one. You also have the option of viewing images uploaded by people you’re following or checking out what’s popular — nothing posted to other services are shown.

TwitPic also provides you with standard editing options, including a variety of Instagram-like filter and enhance effects, such as cropping, orientation, and brightness controls.

Despite launching its own photo sharing service, many people still turn to TwitPic to upload images to the microblogging site — its functionality is integrated with the official Twitter mobile app. However, uploads default to Twitter’s service, which could leave you TwitPic stream a little bare.

It’s too early to tell how successful the app will be, considering its now competing with the likes of Instagram. However, loyal TwitPic users might appreciate the standalone app. You can download the app for iOS devices today; an Android version has been promised for later this month.
