Agree that the web facility has problems on smaller devices.   One problem is clicking (screen touch) in certain situations such as pulling open a menu or selecting an input area.   I've had some luck (v16.0 or 2014a) zooming in and then doing the action.  Sometimes even that doesn't help.  It's not just a fat-finger thing, as my Note 4 has a good pen and even though I click on what looks like the right spot, something else nearby is triggered.  Frustrating, but usable in a pinch ... would love to hear of other workarounds.  I don't use a tablet enough to comment.
