6tag, a new third party Instagram client, is now available in the Windows Phone Store. The app, which as been developed by Rudy Huyn, has gone through a long beta period, reflected in a full feature set and polished design. 6tag provides access to the full range of Instagram functionality, most notably video uploads and the ability to share to multiple social networks.

6tag stands out from the crowd of other Instagram apps available for Windows Phone by having a distinct visual design, which will be familiar to those that have Huyn's other apps (e.g. 6Sec Vine client). Those familiar with the official Instagram app on other platforms will immediately recognise the core functionality and basic layout of the app, but there are plenty of Windows Phone twists, including excellent support for Live Tiles, and integration with the standard sharing framework. 

6tag allows you to upload an unlimited number of images for free, with photos drawn either from the photos+video hub, or captured within the app. As with other Instagram clients the ability to apply filters to photos is supported. 6tag has "100% original filters" (XPro-II, Earlybird, Rise, Amaro, Hudson, Lo-fi, Sutro, Toaster, Brannan, Inkwell, Walden, Hefe, Nashville, 1977), and there's also support for linear and radial tilt-shift blur effects for extra depth of field.

Also supported, in a first for Windows Phone, is the ability to upload videos (with cut scenes) to the social media sharing service. One video upload is included for free with the app, but additional upload will require a one-off in app purchase.
