First Look: Favit, a Twitter Favorites Best-Of Browser
You can navigate the tweets by swiping forward or backward. And nicely the app remembers the last tweet you looked at when you return. And you won't see the same tweet twice unless you go through every one of the millions of favorited tweets.
When you are looking at a tweet, you can favorite it yourself, email it, retweet it, or add the author to your Favstar favorite authors list.
The app is a great, simple way to discover both interesting tweets and interesting people to follow. The app is simple, but it's designed to be that way. Just a small little app to flip between a few new to you tweets to pass the time while in line at the DMV. Well, that's what I used it for last.
