Until the past week I've been using an iphone. Having upgraded and got an android phone, the app for this is bloody awful.
Watching threads it doesn't indicate when you've read the thread or if there's new posts. I have to remember how many replies there were when I last looked or I am constantly having to go on to the post to check. I know it's a minor irritant but also have to scroll down rather than going back and it's in the same place. So I am having to do this multiple times if I click a thread I am watching and it's not had any new replies. It's time consuming and irritating.
It feels like the android app is a second thought compared to how well the iPhone app works.
