Im going to between 10,000 and 15,000 images uploaded to Flickr. I mainly work on my desktop; however, when Im out and about and want to show someone in the image, this app is is perfect.
Several times per week I find myself using the search function to find a particular image. Even when using a mobile connection, your search function is fast, even though I have a large archive.
I do very little "work" in the app. I might change the privacy from private to public, or add a comment, but thats about it.
So, as a viewer, working with a large archive. I think the app is perfect.
