FlickStackr for iPad is a Flickr browsing application. The interface is beautiful, intuitive, and a pleasure to use.
With FlickStackr, you can browse photos on Flickr, even if you don't have a Flickr account. If you do, then you can also browse your photostream, sets, favorites, groups, and contacts. FlickStackr also displays EXIF data, tags, and comments. The main feature that is missing from FlickStackr is the ability to upload photos. However, iPont promises to bring that ability in a future update.
In addition to the wonderful online photo viewing that FlickStacker brings to iPad, it also allows you to save photos locally for offline viewing. iPont calls this feature a "Stack". You can choose any photos from Flickr to save to your stack. It only saves the actual images, however, not the EXIF data that's associated with them.
FlickStackr is an excellent app for experiencing Flickr on the iPad, and for only $0.99, it's quite a steal!
