1. the latest update removed all the best features!! how could they do this to such a good app!!
2. There's not much to say; it checks emails, has a slick UI, and lets me focus on what I need to do.
3. It's pretty good.
4. The app's UI is amazing, but it doesn't seem to notify me consistently which really sucks. Not sure what's up with that but if they could get that working then it'd be amazing.
5. I can't believe how terrible this app is; it literally won't do anything I ask it to.
