What is the name of that cool location app?

For the life of me I can't figure out what's the name of a certain popular app.

What's the name of that one where you ask it a question and it provides the answer, using voice recognition, locations, online data, etc?

I believe it was free and then Apple bought out the company.

Can't find it anywhere, browsing the most popular, categories, staff recommendations, etc.

Thanks!

 

Good lord, I was unable to find that one.

Thanks.
