The popular offline web page viewer, Instapaper Pro, has just received a relatively useful update that adds a bunch of new features, including the ability to share articles on Tumblr and Twitter.
Instapaper Pro is an easy-to-use app for the iPhone and iPod touch that allows you to conveniently save web pages for later viewing. The app is able to save pages in graphical or text mode, star recommended articles, save your position, adjust text and font sizes, and so much more. Instapaper Pro is a must-have app for anyone who is constantly on-the-go and just can't find time to read important articles during the day.
Instapaper Pro v2.1 now features the ability to share articles on Tumblr or Twitter with built-in client support, send articles to supported Twitter apps if you have them installed, email articles without leaving theInstapaper, non-article screens no longer rotate, interface and speed improvements, and fixed a common crash from the previous version. It's worth noting that this version now requires iPhone OS 3.0.
The update hasn't quite propagated to all servers yet, so if you don't see the new version just check for updates on your device. Otherwise you can wait it out, it will show up in iTunes soon enough.
Instapaper Pro v2.1 is now available in the App Store for $4.99. A free version is available, but it is lacking many of the features contained in the Pro version, and it is ad-supported.
Embedded below is a video demonstration of some of the features introduced in the previous Instapaper Pro v2.0 update.
