Great list!

I love the development we're seeing in modern mobile web apps. The web is definitely ready but still everybody around me seems to think that when you're the owner of a business then you should also provide your users with a special app on Android and iOS and a web site.

For example: A nightclub in a nearby provincial town as an iOS App for announcing new parties.

I think that you only should consider creating an app as a business if you're doing more than providing your customers with information.

A great modern mobile web app I'm using a lot is: http://cheeaun.github.io/hackerweb/#/

If you save it to your homescreen on Android(Chrome), you will quickly forget that it's a web app.

Trust me and try it!
