From the iTunes page, this app basically
allows you to save web pages and entire websites, including formatting and images, and read them offline.
First time it's free according to Appshopper; original price is a little inflated but hey- can't beat the current price.
Do take note that this app has a non 'pro' version which is currently free as well. It's quite limited in terms of functionality compared to the pro version.
/update 3 November: the app becomes free again after a brief period of reverting to its original price!
Any advantages over Pocket/Read it Later or Instapaper?
