Does Tweet caster do retweet with comment? Does it search GPS nearby tweets? Does it show the app used for a tweet? Does it have different colors for replies and tweets? Does it show a thorough account profile.
It's very expensive to test. I just think that the 5 star reviews are self promoting. No one reviewing Tweet Caster is subjective.
I'm picky about how my twitter apps handle the timeline. I want to start where I was last, and read from there. The only app that even remotely handles things the way I want is TweetCaster. I love it and i've tried every other major app out there.
I like tweetcaster and Touiteur. The main reason I use Tweetcaster is I can't seem to find an easy way to insert users into a tweet like tweetcaster. Anyone using Touiteur know how to insert users into tweets without manually typing them in?
