Not sure how to say it, but is there a way to let an iOS device (ipad and iphone) "know" that an app is there? As I'm sure many of you do, I have apps that are derivatives of web sites, from companies that send me mail. However, each and every time, on either device, I click on a link in an email, they always ask me if I want to install their app, prior to sending me to their web site. (Like Groupon, or Houzz, etc) I already "have" their app. Is there a way to toggle a setting or something to make these "sites" self aware than an app is installed, and not ask me to re install, and then send me to a web site instead? Great idea by the way, if there's not...... I call dibs on idea!!
