iDiagram: Good app with potential of becoming the competitor of iCloudy. Problem is UI seems little less polished. Lines don’t get auto-snap. Apps that provide a flow-chart / mind-mapping capibility should keep the focus on basics of the kind of tool usually offer. Line should get auto connect when another object dragged on board. The text in the box should auto-expand / wrapped. Overall okay UI experience. Kind of put me in to the thinking mode more than once
