Twitter launched Vine, the video sharing service, at the beginning of this year and now the app is available on Amazon Kindle Fire.

Vine was initially launched only for iOS, and on June 3 the app was launched for Android platform as well. Amazon Kindle Fire tablets run on the open source Android operating and cannot officially download apps directly from Google Play store. Instead Kindle Fire users have to download apps from Amazon App store.

Vine allows users to capture and share unlimited number videos to a maximum of six seconds. You can instantly post videos on Vine, then share to Twitter and Facebook. You can also explore trending posts, featured hashtags and editor's picks.

The Amazon product description of Vine says, "Vine is the best way to see and share life in motion. Create short, beautiful, looping videos in a simple and fun way for your friends and family to see. Have questions, problems, or feedback?"

The increasing popularity of Vine coupled with competition from other video sharing apps like Instagram may have prompted Vine to launch its app in the Amazon App store.  

A TechCrunch report says, "After Twitter debuted an Android version of Vine in the beginning of June, usage reached a tipping point: shares of Vines surpassed those of Instagram photos on Twitter - usage that has only diverged even more since then."

It seems that Twitter has successfully attracted many Android users to its video sharing app. We will have to wait and see if Twitter successfully tempts Amazon Kindle Fire users with the launch of Vine on Amazon App store.  

You can download the app for free from Amazon App store. The size of the app is 18.1MB.
