Refresher proves to be a very useful tool: it automatically refreshes your web pages and notifies you when the source code of the page has been modified so that you can preview the changes in real-time.
Nevertheless, the program provides a lot more functions that I found to be really helpful: an Auction Template (a handy assistance tool for when you bid on auctions), an I.P. Tool (that you can use to fix I.P. addresses or domains), a PC Timer and a PC Reminder. In addition to this, Refresher also provides a countdown for refreshing pages and a tab cycle frequency.
However, at a certain point, because of the license limitation of the trial version, the application will close by itself but it gives you a 20 seconds warning.
From my experience with the application, I've found out that Refresher can also be very effective when monitoring a web mail account. Whenever you are expecting an important mail, you can use Refresher to automatically notify you in case of new messages. Still I consider it to be a little bit too expensive.
