If this app is as great as it is touted - with all the innovation and technology - why is such a simple thing like left-handedness not part of this innovation? I guess it is a question of the right hand not talking to the left. Imagine. This programs gets my left-hand smudge as a rating. (In all fairness I posed this question directly to the development team about four months ago, was acknowledged and identified as a feature request. There have been several several iterations of the app since). If you are left-handed I recommend you give this app a pass.
