So some app can be downloaded for free from the Google app store? That's not news; that describes millions of apps! I'm guessing this is your app? Tell us about your app, and what it does, and why you made it.
Don't listen to your PR department! PR departments don't want to say anything real. They think that pretty pictures and flowery language are better than telling people about the product they're selling. But you're not a PR department, you're a developer. You developed this app, and you developed it for a reason. It deserves better than a mere pretty picture.
