Is this domain a trademark infringement?

Hi, i was wondering if i could open a site called "Apps like skype" (on a domain apps-like-skype.com or something), and have reviews on it on apps that are similar to skype. I think it is allowed because the users who get there know that i am promoting a product that is not skype. A friend of mine told me that is trademark infringement and skype can sue me for building such a site. Who is correct ?
