Crashes and Unresponsive – Blur It Free Review

For the most part it works pretty ok when it comes to blurring or putting a smiley face or whatever on the pic but when I try to undo, it only undo once but when I keep on pressing the undo button it quits automatically, it's not a bad app but they should really brainstorm a little more to see how they can make this app better
Review by don't worry it's me on Blur It Free.
