Must have app for Flickr Users

I really like to use this app to upload and view my photos on Flickr. It will take my photos from iPhoto or on my mac and send them to Flickr. I know that I can do this with iPhoto, but doing it will iPhoto does not work as smooth. This is much better. I can also view my Photostream in this app, and do way a whole bunch more. This app is a must for people that use Flickr.
Oh and the maker of this app answers his emails if you need help.
