Rotten Tomatoes and Launch Center
I appreciate Rotten Tomatoes, I don't always agree with the ratings, but I like how they can add to an argument or conversation about a movie.
I hate the Rotten Tomatoes experience on an iPhone. It starts with this horrible app pop-up:
Then it nags you to add the site to your homescreen, my home screen is meticulously planned out and I don't have the room for non-apps, so Rotten Tomatoes can go kick rocks.
A month or so ago I decided to do something about these things that bug me about Rotten Tomatoes. I spent an hour or two poking around the API and cobbled together Diet Rotten Tomatoes. It's a quick, lightweight way to get a movie's ratings, a full-size movie poster (click the thumbnail), and a link to the movie on Rotten Tomatoes.
Hopefully you find it useful.
