Rainbow HD 4+

This is going to be a great app. Needs a bit more work, but I think when it's done, it may very well be a top seller. Needs a bit more control for the perspective settings, additional border layers, and the background color setting is a little buggy, some of the bounding box math needs a little work, but all in all, it's gonna be a great app :) For what it's worth, I have been coding transformations like this for over 25 years, and when I get off of work, I like to play with this app (that says a lot). I hope the developer continues to add more transform features, and if this is ever a pay for app, I hope to be the first paying customer. I might even want to buy the company! Best if luck, and thanks for the latest update. TJoe(j^).

Update: developer improves resolution limits. In the original offering, For such a sophisticated, feature-rich and well appointed app, I was extremely disappointed to find that the final saved resolution of an image was a dismal 1024x954.

However, the recent update removed the limitation, and now images up to about 8 or 9 mp can be "edited" and saved, depending upon what effects are applied.

Lower res images in the 5-6 mp range are clearly not a problem. Although the app will load and manipulate 12mp images, trying to save the results yields a crash, so downsample your images to 8mp and you should be ok.

The developer listened to the users, and promptly corrected the issue. Well done!

Should have let people know that a few important features were missing, Tilt Shift, and page curl. Website and video shows these features but I found out that only the desktop model has it. All other features are not needed. Free apps have better results
