Comparing Twitter App Timeline Views ⇥ imore.com
Rene Ritchie of iMore has compiled a selection of the timeline views of fifteen popular Twitter apps (plus three discontinued ones) for the iPhone. There’s a certain amount of overlap, but many of these are clearly distinct — Tweetbot won’t be confused with Twitterrific, and UberSocial is different from Flurry.
Compare that against a selection of seventeen Android Twitter clients from Phil Nickinson of Android Central. I count eight in there that are nearly identical.
