Draw Expres has a very nice interface for mobile. It's simple and not overly cluttered compared to those tools that adhere strictly to notation standards. I'd give it more stars however trying to upgrade has highlighted some issues. Firstly the paid version does not support the latest version of Android? And then no response to a query. It seems the developer has not updated their website in a few years.

Just started playing around with this app and so far is great and I'll probably buy the full version. My only complaint so far is I can't find a way to just "un-select" something. Like after I draw a line the line stays "selected" and I just want the selection controls to go away. Usually just clicking off the line would do it, but that tries to add another line. Not a deal breaker, just a minor UI gripe.

They worked hard on this to make it interactive, but when a gesture doesn't register the way you wanted, it leaves this random scratch over your diagram, and if you hit "undo", it leaves the mistaken squiggle and deletes whatever you added before it. If you use the erase gesture on the squiggle, it could delete the squiggle, a part of your diagram, or both. For me, it would be more efficient to select from a list of components and have it always add the right thing, even if I have to move more.
