Jelly 2.0 is a refined and better version of the erstwhile Jelly Q&A app. Available as a web service and also as an iOS app, this new version lets you ask questions anonymously. The app then directs the question to someone who can answer your query. Unlike other Q&A apps, Jelly is smarter and is not content with just answering the question. For instance, if you posed a wrong question, the app would let you know so. Also, the answers you get would be in much more detail, more than what you asked for.
