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.
On the "Still needs work" side I am finding that the signature filters seem to apply very high contrast and in fact blow out the highlights. I have checked several images and find the histograms to be within limits. They may be toward the right but not to the point that information is lost. The image of the trees with spider webs is an example of this. Although a high contrast style is quite often very eye catching it's certainly not the only "look" for a photographer.
To be fair this App has only just been released...version 1.0 so to speak. Here's hoping for further refinements.
