I have to build an app in iOS. I need to know if this app can be done... is this a doable app?. App requirements The app should start automatically when the user opens a browser in his/her cell phone. Or the app could start with the Operative System and be executed all the time in the background. The app will detect when a browser is open and the app will read the browser's window content (html or text) and then the app will show a form if a tracking number (from usps, ups, fedex, etc) is found. Thank you for your help.
