Needs improvement, but only option I could find
I tried this app as a replacement for Auto Stitch, which was a fantastic panorama stitcher but is unfortunately no longer in production.
This app gets two stars mostly on the basis of being the only app I could find that will at least attempt to stitch existing pictures together.
The interface is clunky and the output quality is poor, low resolution. There is no settings area where you can adjust the output quality.
Also, the "rate 5 stars" button that appears after every stitch is annoying.
