## Most critical reviews (4 lowest-rated)

### 1/5 — What happened to the other features?

*2013-03-15*

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

### 1/5 — not good!

*2013-03-03*

You can't crop with your fingers only by sliding buttons. You can see values but you are not able to type in a value the same with the resize function. It's more or less useless. Waste of $0.99!  Sorry to say this.

### 4/5 — Sweet Effects...Resolution Imroved!

*2012-11-03*

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!

### 4/5 — Gonna be a great app!

*2012-02-26*

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^).
