Whileaway is a Twitter client that shows your favorite users' tweets in *stories* format. It is a better version of Twitter's 'while you were away' that puts users first. Here you get to choose your favorite accounts and Whileaway makes sure you don't miss any of their tweets.
@simoalx I was using lists initially, but I always felt Twitter never made any effort to improve the experience around the lists. Thought bundling users tweets would solve this problem better, hence created this app. But if lists work for you, then, ofcourse, no need for this.
