SearchTrends: What's hot in search engines?

SearchTrends for the iphone displays real-time search for Google, Bing, Yahoo and Twitter and lets you search on those terms real-time instead of gearing to traditional news sources to discover the goings on in the world of news, events and search.

Compared to UI, which displays only text, Search Trends compares data across the three search engines simultaneously; in future, graphs and data charts would conveniently help comparisons without browsing each site.
