The extremely popular social photo sharing service Instagram now has a very serious competitor to it's own app -- it's called Gramory. Gramory offers a superb way to browse through Instagram photos. One of the huge features that is not present in Instagram's official app is the ability to browse by trends.
Gramory has a very nice, multi-panel UI. The left panel is where you'll be able to choose how to filter the photos that you're browsing though. You can look through your own photos or feed, the popular photos, photos that you've liked, or even see what tags are trending and browse through those images. Regardless of which view you choose, you'll see them all presented as thumbnails. This is awesome because it lets you see 20 photos at once on a single page so that you can select which ones you'd like to see larger.
When viewing a photo, you'll see a large version of the photo as well as all the comments that have been made on that photo. If you pull the screen down, you'll see the hidden icons that let you share the photo to Twitter, Facebook, Messages, or Mail. You can also like the photo or leave a comment. If you tap the little thumbnail icon in the upper righthand corner, a left panel will slide out that displays thumbnails of that user's Instagram photos.
Despite how awesome Gramory is, it's still not a replacement for the official Instagram app. It doesn't allow you to post photos, nor can you see a nice list of recent comments and likes made to your photos.
If you're a big Instagram user, you must start using Gramory. It's offers a new and better way to browse photos posted to Instgram.
