Ratio'd is a Chrome extension which is capable of highlighting tweets with exceptionally bad ratios on Twitter. It was developed with the intention of finding tweets which are extremely unlikely to receive any likes and/or retweets, as well as posts which receive very few of them. 

The reason behind this is that sometimes a tweet can receive many likes but few replies, in a way that the tweet becomes very uninteresting for many users. The idea of this extension is that it makes you aware of any tweet you might be interested in by placing a small indicator next to the tweet. If you feel that a tweet is noteworthy, then you can then click on it and it will take you to the tweet.

This extension will be useful when you want to examine any posts you might be interested in and make sure they are not exceptionally likely to receive any likes and/or retweets.

You can configure the extension to show you only the posts which have a negative or positive ratio.
