Great app for curbing Twitter addiction!
A couple of things could improve the app: First, after clicking on a link within tweet, you are returned to the top of your timeline--so you have to scroll all the way down to where you left off. It would be a huge help if it kept your place & returned you to where you left off.
Second, a "read later" function for longer articles (using Readability, for example), would help allow you time "off the time" for longer articles. There was an "add to reading list" option, but when I pressed it it took me to the article, with no way to return to my timeline. I had to close the app and restart, burning one of my allotted allowed sessions.
If these things were fixed, 5+ stars for sure!
