I find myself feeling that this looks a lot friendlier than Dropbox for iOS. I'm split between Android and iOS devices at work, and I'm consistently finding Android apps a lot softer and gentle in their material redesigns, whereas iOS seems to be going the opposite way sometimes. I think it has a lot to do with the font weights and the encouraged 'default' text size for devices. Will be interesting to see how this changes when it's Roboto vs San Francisco rather than Roboto vs. Helvetica Neue in terms of a UI font.
