Interestingness! is a free Flickr browser that allows you to find the top photos from Flickr for any given day and then open and interact with those photos. The app offers few tools for searching or browsing photos other than the calendar, but for anyone who enjoys sifting through favorites and then interacting with those images, leaving comments, sharing, or saving the photos, this app will get the job done.
The first thing you see when opening this app is the home screen with today's top photos. By default, 500 photos will load from Flickr, matching today's date. You can change dates by tapping the calendar button or scroll back one day at a time. If you tap on any of the photos here, you can get a URL, favorite it, share it, comment on it, download it to your device, or see the profile of the photographer. From any of these screens you can view more photos, seeing what that photographer has shared, what they like, or what their fans have favorited. The interface in Interestingness! seems clean at first, but as you dig deeper into the menus, there are many hidden options, sometimes to the point that you can get lost in them.
Interestingness! is not an effective search tool for Flickr. By default, you'll be browsing photos at all times. But it does work well for finding new and exciting images, photographers, or collections you may not have seen before. The app is free with a single ad bar at the bottom supporting its use and it runs very quickly and very smoothly -- a top pick for Flickr browsing.
