This app seems to have the absolute best algorithm for creating very natural looking HDR photos based on 10+ HDR apps I have tried. It is truly magical how the brights are protected and the shadows are open while the viewer would never know that it is an HDR shot. However, the app has little or even no alignment mechanism and as such the photos are unusable. Since the developer has been dormant for three years, it looks like this will never be addressed. This is tragic, because this app could easily be the hands-down leading HDR app in all of iOS.
