On the positive side it can help create some lovely images and it is easy to send the results to wherever I like. In the image of the red tug I used the App to apply a (double) vignette, warm the image, crop it square and apply a white border. Very easy to do and I like the results. Also, it saves the results at full resolution which to me is a big deal. My favorite App of all "Camera Bag" doesn't seem to be able to figure this out and so I don't use it as often as I might.
To be fair this App has only just been released...version 1.0 so to speak. Here's hoping for further refinements.
