Your days of endlessly hitting “Refresh” to see if a price has come down may be over (unless you like that sort of thing). Punchr is a new app that will monitor any part of a web page for updates and then let you know when it happens. You just navigate to the site and then select the part of it you want to look out for, and it’ll send you a push notification if something changes.
So now you can spend less time refreshing Twitter when it’s down and more time taking pictures of your lunch to post on Twitter when it returns.
