Actually, I doubt most people know what a "web app" is. Have you ever tried to explain the difference between a Web Site and a Web App to someone non-technical?

Actually, I doubt most people know what a "web app" is. Have you ever tried to explain the difference between a Web Site and a Web App to someone non-technical? Apps, on the other hand, are definitely understood to be mobile applications. Can't say whether it's tied specifically to Apple or not though. That's not to say I agree with App Store being trademarked - it's pretty ridiculous, IMO.
