App or website???

I guess I'm getting old, because I dont understand the point of applications?

Ebay and Amazon are one I use the most.

Why would I want to download something that takes up space on my mobile device, when I can just go to the website?

Amazon app is ugly , The layout of apps always seem more difficult.

I know there are some apps that are a must.

, but seems like they want one for every website.
