If you’re like me an often come across useful links and tweets in your Twitter feed I can’t recommend this combination enough. I’ve used several different Twitter apps on my iPhones but the app that has one out for me is the actual app from Twitter. The app used to be called Tweetie and was a paid app. However, Twitter bought it in April of 2010 and made it free. Thanks Twitter!
I also use Instapaper to keep track of items on the net that I don’t have time for when I come across them but want to read later. I used Instapaper infrequently prior to using the Twitter iPhone app but since finding the built in integration my Instapaper use has exploded.
It’s so useful to be able to go through my Twitter feed when I’m stuck in a line-up or at a red light and add them to my Instapaper list in a couple taps. Then, when I have a bit more time to kill I can fire up Instapaper the app and read all those juicy items I didn’t have time for previously.
