The main dashboard of the Flickr app opens directly to your activity feed, which lets you know if anyone has favorited or commented on any of your photos. From there, the navigation bar at the bottom of the screen can lead you to the app's other areas, including your own profile and Contacts. In addition, there is a new Explore section, similar to Instagram's, which shows you Interesting (popular) photos on Flickr, as well as photos that have been geotagged nearby. Clearly, the folks at Flickr want users to do more than just upload photos; they want them to hang around, browse, and connect with the community, just as they might do on Instagram.
If you're looking for a powerful photo manipulation tool, then Flickr probably isn't it. It offers 16 filters, the ability to caption items, and that's about it. What Flickr is really good at, though, is sharing. It can share natively to Facebook, Twitter, Tumblr, or e-mail. Plus, it lets you download any photo from Flickr in just a few taps.
Something you can't do from the mobile app is customize your profile. There are no options to edit your personal info, but you can upload your profile photo. Also, you can't organize your photos into sets from the app after they have been uploaded or create groups.
The latest update to the app brings several features users have been looking for to add more convenience. When you snap a photo, Flickr automatically saves it to your iPhone photo library before you start adding effects. You also can now save photos from your Flickr stream to your photo library as well. You can finally tag contacts in your photo captions and descriptions to notify them of the images you've uploaded. In Lightbox mode, your images will now appear in higher resolution, making the Lightbox mode much more useful for differentiating between similar shots and giving the mode a better look overall. Finally, Flickr now uploads images much faster than before. None of these tweaks is particularly ground-breaking, but I think many people will agree that some of the small annoyances of the past have now been addressed.
Still, if you're looking for a tool to share your mobile photos and back them up to your Yahoo account in the cloud, then Flickr is a great choice. It may not be able to do everything, but it handles the basics pretty well and offers a ton of beautiful photos to browse.
