The Ask.com app? I would assume it gives you access to Ask.com and you can use it like you would the website. You might want to be more specific in your question though, not all of us are using the app and so might get confused.
The Ask.com app? It's almost exacty like the website!! You can check your q&a, browse questions, edit your profile, and browse the internet! The only think I cant figure out is how to answer the daily question on the homepage.
