If I could have a regular mobile reading experience using my browser, pray tell why I would want to switch to your awesome app (TM) ? I detest "download our app" popups with a passion. The worst part is that most of these 'apps' just have the same experience packaged into them but are located under yet another icon on my iPhone/iPad. It just doesn't make any sense.
The only other place that I read besides the browser is Pocket.
With responsive design and HTML5 (Geolocation, Canvas, etc.) there really isn't that much more that an app can do - that a browser cannot.
Also, asking to me repeatedly download your app (tripadvisor, you're guilty!) is probably going to alienate me even more from it.
A good example of an app doing less than the website: Until recently I couldn't use the hotels.com app to score/redeem welcome rewards. Yet, when I would go to the site I would either be:
a) Limited to the mobile site
b) Treated to a heinous app download popup.
Way to go!
