iOS: It's not like searching the web on your iDevice is particularly difficult, but getting quick information from various sites can take some time. Search makes web searches much faster by letting you type in your terms and just go.
The way Search works is very simple. There's a search box up top, you type in your search time, and you tap the icon of the tool you'd like to use to search for results. Currently you can choose from Google, Yahoo!, Wikipedia, Dictionary, YouTube and Flickr. Results are brought up in an in-app web browser so you don't have to leave the app. Search doesn't do much, but it will save you a fair amount of time in your specialised web searches.
While the Search app is free, it comes with ads. A pro version is available for $6 and lets you add practically any search engine. If there's a search box, you can simply browse to the page, tap the search box, and save it as an option in Search Pro. We're not sure that's worth $6, but it is a pretty neat feature.
